Modular Suitcase ################ :date: 2015-08-04 23:30 :modified: 2015-08-05 18:40 :tags: diy, modular, suitcase, eurorack :category: hardware :slug: modular-suitcase :authors: David Runge About ----- | From the beginning of 2015 on I started building some :abbr:`Eurorack (A racking system for modular synthesizers, being 3U tall and a multiple of 2HP wide)` synthesizer modules designed by |befaco|. This, being one of those :abbr:`GAS (Gear Acquisition Syndrome)` related activities, easily gets out of hand of course and leads to the final question: | Where to put all of that stuff? | The usual answer to that question is to buy a premade suitcase (by Doepfer and alike) or a semi-fitting suitcase, that you can modify and put rails into. | Being a :abbr:`goat skinner (Someone who tends to find the most complex way of acquiring a functionality. Usually by building all components him/herself.)`, that obviously wasn't enough for me. So I started building a suitcase on my own (with some inspiration from |victor_mazon|), trying to adhere to cabin luggage size limitations (40cm x 50cm x 20cm) for most airlines, just to learn that the :abbr:`IATA (International Air Transport Association)` changed their suggestions when I was about to start building. Although being a suggestion, it is most likely that many airlines will stick with this new size limitation (55cm x 35cm x 20cm), which is sad, because with a little over 40cm you can actually fit in 3x 3 :abbr:`U (Rack unit)` into your suitcase! Nevertheless, I decided to move forward with my initial size limitations for my suitcase. It can host 6 x 19" of modular Eurorack goodness. **Note**: My modular suitcase is designed to fit with up to four |befaco| |power_busses| and one accompanying 2A |d-60| power supply. It can host modules of depth up to 5cm on the upper side and modules of a maximum depth of 7cm on the bottom side. This may or may not be what you are looking for. **License**: All information, pictures and other files on this page are |cc| licensed. **Yadayada**: This is all very nice, but take me to the Pictures_! .. |victor_mazon| raw:: html Victor Mazón Gardoqui .. |befaco| raw:: html Befaco .. |power_busses| raw:: html Power Busses .. |d-60| raw:: html WEHO D-60 .. |cc| raw:: html CC BY-SA 3.0 Planning -------- I'm not a fluent :abbr:`CAD (Computer-aided design)` software user, so I decided to use |inkscape| (a powerful, free and easy to use vector graphics tool) for planning the whole thing instead.

html Suitcase (front) Material -------- | Some of the modifications to the above layered SVG files I have been doing while building the suitcase. So, if you want to build one your own, make sure to have the time for proper planning (and changing of plans). | Most of the materials you can either order via |thomann| or find in your local hardware store. For some of the bolts/ screws I went to special stores though. Tools will be discussed further down. Ready mades *********** Here's a list of things I bought for the suitcase: ======== ================== Quantity Item ======== ================== 5 |adam_hall_6106| (aluminium casemaker) 5 |adam_hall_6202| (aluminium closing profile) 8 |adam_hall_40402| (zink plated steel corner brace) 8 |adam_hall_4000| (zink plated steel corner) 7 |adam_hall_blind_rivet| (20 x 4,8mm x 15mm blind rivets) 4 |adam_hall_1602tp| (cheney-lock with eye, galvanized) 1 |adam_hall_3415| (handle) 12 |19inch_rails| (19" rack rail, without edge) ======== ================== Screws, washers and nuts ************************ | The 24 rail screws need to be |m5| (5mm screw thread, 2,5-3cm long). Choose proper steel screws with small (nugget) heads (around 8mm in diameter)! | The 28 screws used for the cheney-locks and the handle (also |m5| I chose to be proper steel security torx screws (2cm long) with 28 accompanying self-holding nuts. | The |befaco| |power_busses| and the |d-60| power supply will be attached to the suitcase by |m3| (1,5cm long) screws with fitting nuts. You'll need 4 of each per Power Bus and 4 of each for the power supply. | For each applied blind rivet it's good to have a washer (applicable for |m5|). You'll need 140 of them (roughly 1,5cm in diameter). | Another form of washer is needed to be put between the 4 inner rails and the plywood. It has to be 347mm x 275mm x 1,5mm. I chose a very cheap aluminium bar in a local hardware store, that - aside from an edge I had to saw off - fits the description. | | **Note**: Interestingly enough the aluminium bar used for the rails washers proofed to be very useful as an upright anchor for the |d-60| power supply, too. To properly use blind rivets going through the casemaker on the side of the power supply for holding the anchor, it has to be 20cm long. The bar I used is L-shaped, 2,7cm high and 1,4cm deep. The rivets will go through the shorter side of the bar. Plywood ******* | To properly fit the above mentioned aluminium casemaker and closing profiles I recommend plywood of no more than 6,5mm thickness (especially if you still want to apply some paint). | Many hardware stores pre-cut plywood for you, but it might not be sufficently accurate. The following dimensions have to be accurate! ======== =============== Quantity Dimensions ======== =============== 2 43,2cm x 7,5cm 2 43,2cm x 9,3cm 2 38,7cm x 7,5cm 2 38,7cm x 9,3cm 2 43,2cm x 38,7cm ======== =============== .. |thomann| raw:: html Thomann .. |adam_hall_6106| raw:: html Adam Hall 6106 .. |adam_hall_6202| raw:: html Adam Hall 6202 .. |adam_hall_1602tp| raw:: html Adam Hall 1602TP .. |adam_hall_40402| raw:: html Adam Hall 40402 .. |adam_hall_4000| raw:: html Adam Hall 4000 .. |adam_hall_3415| raw:: html Adam Hall 3415 .. |19inch_rails| raw:: html 19" rail .. |adam_hall_blind_rivet| raw:: html Adam Hall Blind Rivet .. |m5| raw:: html M5 .. |m3| raw:: html M3 Building -------- | For building this kind of suitcase you'll need proper tools, or you'll easily be very very frustrated (so, please take this as a warning). | At home I only have a small working area for soldering and such small activities, but no proper work bench. So I used a nice |hackerspace| (of which there are plenty in Berlin) as workshop. |c-base| is one of the oldest (founded in 1995) and has many tools to offer (to its members). Tools ***** You'll definitely need the following tools: - circular saw bench (if the plywood could not be cut properly by the hardware store, or you just want to do that yourself) - bench drill (choose this over a standard drilling machine for more accurate and straight drill holes) - 5mm metal drill head - 5mm wood drill head - 3mm metal drill head - 3mm wood drill head - sandpaper (80 & 120 or 240) - hammer (always good to have one) - metal saw (with thin - preferably a set of exchangeable - saw blades) - cordless screwdriver - |bosch_gop| (or similar tool, for sawing in strange places) - rivet gun/ riveting tongs - a brush and matte paint (for the finish) A note on cheap tools, especially cheap riveting tongs: If you buy the cheap stuff, it'll hurt your hands and it will break after a short while. The one I bought lasted around 70 blind rivets and then it gradually started to degrade and not get a grip on the rivet bolts any longer. Save yourself the trouble and find a space with a high pressure rivet gun or get high quality riveting tongs. It's worth it. .. |hackerspace| raw:: html Hackerspace .. |c-base| raw:: html c-base .. |bosch_gop| raw:: html GOP .. _Sawing: Sawing ****** | **Note**: When sawing the aluminium casemaker and closing profiles, make sure to wear a mask. This kind of fine dust you don't want to breathe in. | You'll need the following quantities and lenghts of aluminium casemakers and closing profiles: +--------+--------+--------------+ |Quantity|Length |Component | +========+========+==============+ |4 |33,2cm | Casemaker | +--------+--------+ | |4 |37,7cm | | +--------+--------+ | |4 |2,65cm | | +--------+--------+ | |4 |4,45cm | | +--------+--------+--------------+ |4 |33,2cm | Closing | +--------+--------+ Profile | |4 |37,7cm | | +--------+--------+--------------+ |1 |20cm |L-shaped | | | ||d-60| anchor | +--------+--------+--------------+ | Make sure to saw straight and clip the material afterwards (the cutting edge will be sharp!). You might burn some saw blades on this. Aluminium easily smears when being sawed. | .. figure:: /images/modular_suitcase_corner_casemaker.jpg :alt: Corner casemaker Corner casemaker To make the |befaco| |power_busses| fit into the suitcase, a little opening has to be sawed off. For this you should use a tool like a |bosch_gop|. .. figure:: /images/modular_suitcase_casemaker_shortening.jpg :alt: Corner casemaker Cavity for the |befaco| |power_busses|. This has to be around 0,4cm x 7.0cm and starts from around 6,6cm from each side of the 4 shorter (33,2cm) casemakers. The rails washers for the top part of the modular suitcase have to have a little edge be sawed off. This is needed to be able to properly put a blind rivet for the corner there later on. .. figure:: /images/modular_suitcase_rails_washer_edge.jpg :alt: Rails washer with sawed of edge (from top part of the suitcase) Rails washer with sawed of edge (from top part of the suitcase) | Once you're done with the metal sawing (and you hopefully already have the proper plywood parts done), you can start combining them with the plywood. | .. figure:: /images/modular_suitcase_bottom_pre-drilling.jpg :alt: Combination of plywood, closing profile casemaker and corners Combination of plywood, closing profile, casemaker and corners before drilling .. _SawingRailsSlice: | **Note**: Four of the rails will have to have a slice of 1,5mm by 2,1cm be cut off. It has to be on the side where there's no nut rail (bottom side on the below picture). This has to be done, to make the rail fit properly in the suitcase right next to the plywood and thus ensuring 3 :abbr:`U (Rack unit)` also on the outer rack spaces (otherwise the corner casemakers push the rails inwards and thereby waste 1,5mm). .. figure:: /images/sb_rail.jpg :alt: 19" rail (without edge) 19" rail (without edge), as used in the modular suitcase Marking ******* | Mark all your components and their proper positions, once you have them pre-assembled. This makes drilling much easier. I numbered all plywood components with a fineliner and scratched in numbers on casemakers and closing profiles towards the respective piece. - For all non-corner casemakers and all closing profiles their position on the plywood is easily determined (by the length of the corner pieces). They have to have a distance of 2,75cm to each side of the plywood their being put onto. - All casemaker corners must have a distance of 2,7cm to the bottom (of their respective side) of the plywood and a distance of 2,1cm to the top. This applies to both sides of the suitcase. - The rails washers have to be positioned 2cm from each side of the plywood and 4cm and 2,7cm from the bottom of it (for bottom and top of suitcase, respectively). .. figure:: /images/modular_suitcase_sides_closing_profile_and_casemaker.jpg :alt: Closing profiles and casemakers on plywood with markings for casemaker corners Closing profiles and casemakers on plywood with markings for casemaker corners .. figure:: /images/modular_suitcase_rails_washer.jpg :alt: Closing profiles and rails washers on plywood with position markers Closing profiles and rails washers on plywood with position markers | This is also the perfect time to mark the center of each drill hole. Those - like the markings mentioned earlier - have to be applied "from inside" the case. | | **Note**: Use a pointy bolt for hammering in a little notch for each center point. Do this with the plywood in the casemaker and closing profile, else you will bent it! +------------------+--------+---------------------------------------------------------------+ |Component |Length | Center of drill holes | +==================+========+===============================================================+ |Casemaker |37,7cm |1cm, 9,9cm, 18,9cm (from both sides and angles)/ | +------------------+ |each 1,2cm from the opening (for plywood) | |Closing profile | | | +------------------+--------+---------------------------------------------------------------+ |Casemaker |33,2cm |1cm, 7,6cm, 16,6cm (from both sides and angles)/ | +------------------+ |each 1,2cm from the opening (for plywood) | |Closing profile | | | +------------------+--------+---------------------------------------------------------------+ |Closing profile |33,2cm || top: | | | || 2,6cm/ 1,85cm and 6cm/ 1,85cm (cheney locks) | | | || (from each side/ opening for plywood) | | | +---------------------------------------------------------------+ | | || bottom: | | | || 2,7cm/ 1,85cm and 5,9cm/ 1,85cm (cheney locks) | | | || 9,45cm/ 1,2cm and 11,9cm/ 1,2cm (handle) | | | || (from each side/ opening for plywood) | +------------------+--------+---------------------------------------------------------------+ |Casemaker (corner)|2,65cm || side with rail: | | | || 0,6cm/1,2cm, 2cm/1,2cm and 1,35cm/1,7cm (rail), from bottom | | | +---------------------------------------------------------------+ | | || side without rail (from bottom): | | | || 0,7cm/1,2cm and 2,1cm/1,2cm, from bottom | +------------------+--------+---------------------------------------------------------------+ |Casemaker (corner)|4,45cm || side with rail: | | | || 0,6cm/1,2cm, 2cm/1,2cm and 3,35cm/1,7cm (rail), from bottom | | | +---------------------------------------------------------------+ | | || side without rail: | | | || 1,0cm/1,2cm and 3,5cm/1,2cm, from bottom | +------------------+--------+---------------------------------------------------------------+ |Corners (bottom) | \- |1,9cm from each side of bottom plywood corner | | | |(applies to every corner on both sides of the suitcase) | +------------------+--------+---------------------------------------------------------------+ |Corners (top) | \- |0,3cm/ 0,75cm and 1,6cm/ 0,75cm from top plywood corner | | | |(applies to every corner on both sides of the suitcase) | +------------------+--------+---------------------------------------------------------------+ |Rails washers |34,7cm || top: | | | || 10,4cm/ 0,7cm and 11,3cm/ 0,7cm (rails) | | | || 5,05cm/ 0cm (cheney locks) | | | || from each side/ top of component | | | +---------------------------------------------------------------+ | | || bottom: | | | || 10,4cm/ 0,7cm and 11,3cm/ 0,7cm (rails) | | | || 5,05cm/ 1,75cm (cheney locks) | | | || from each side/ top of component | +------------------+--------+---------------------------------------------------------------+ ||d-60| anchor | 20cm | 1,0cm/ 0,9cm from each side and 10,0cm/0,9cm | +------------------+--------+---------------------------------------------------------------+ Drilling ******** | **Note**: Drilling should be as straight as possible. A bench drill is highly recommended! | | Tape the components to the plywood after marking, so they won't move during drilling. | Using a 5mm metal drill head, one can *slowly* drill through closing profiles/ casemaker/ rails washer/ power supply anchor + plywood. The casemaker components have to be reattached to different pieces of plywood to finish all holes. | .. figure:: /images/modular_suitcase_sides_with_tape_and_components_above.jpg :alt: Two pieces of plywood with components taped to it and drilled holes Two pieces of plywood with components taped to it and drilled holes .. figure:: /images/modular_suitcase_sides_with_tape_and_components_side.jpg :alt: Pieces of plywood with components taped to it and drilled holes Piece of plywood with components taped to it and drilled holes .. figure:: /images/modular_suitcase_inside_after_drilling_fail.jpg :alt: Rails washers, casemakers and closing profiles after drilling Rails washers, casemakers and closing profiles after drilling. Chances are good, yours will look better (without the drilling fuckups in the corners) After drilling a disassembly is recommended to clip plywood and aluminium components. This is also the best time for a preliminary test, if all components have the expected dimensions. .. figure:: /images/modular_suitcase_inside_after_drilling_with_rail.jpg :alt: Rails, rails washers, casemakers and closing profiles after drilling Rails, rails washers, casemakers and closing profiles after drilling. Rails ***** The rails used need some further modifications to be put in the suitcase. One, that has to be applied to the two outer bottom rails is an edge that has to be sawed off. .. figure:: /images/modular_suitcase_rail_bottom_edge.jpg :alt: Outer, bottom rail with sawed off edge Outer, bottom rail with sawed off edge (but still with the 1,5mm slice, as mentioned in Sawing_) Another is drilling a hole through the two outer top rails at 0,9cm/ 0,9cm. This ensures, that the the lower of the two blind rivets on the corner pieces of the top part of the modular suitcase can be replaced by one of those |m5| screws. .. figure:: /images/modular_suitcase_rail_top_hole.jpg :alt: Rail from top side of the modular suitcase with hole drilled through for fixing with screw Rail from top side of the modular suitcase with hole drilled through for fixing with screw A third is sawing off a little edge at the outer top rails, to give the lower blind rivet (parellel to the screw going into the nut rail) enough space. .. figure:: /images/modular_suitcase_rail_top_edge.jpg :alt: Rail from top side of the modular suitcase with edges sawn off Rail from top side of the modular suitcase with edges sawn off. Only the right one is correct, the left sawed off edge should be the 1,5mm slice, mentioned in Sawing_ Painting ******** The paint job was quite easy. I applied two rounds of paint. .. figure:: /images/modular_suitcase_first_painted_plywood.jpg :alt: Plywood after one round of paint Plywood after one round of paint. After the first paint job, I used the sandpaper (240) to smoothen the surface and then did a second round. The wood grain is still nicely visible. .. figure:: /images/modular_suitcase_second_painted_plywood.jpg :alt: Plywood after two rounds of paint Plywood after two rounds of paint. Assembly ******** | Now to the final (and *fun*) part. Assembling all that stuff! | The power supply can be attached to its anchor before all the blind rivets will be put in. For this you have to drill two more holes with the 3mm metal drill head. The drill location depends on the screw locations on the power supply. You will have to open its chassis and put two of the |m3| screws there. I used a bunch of nuts to bridge the gap between the power supply and the anchor. .. figure:: /images/modular_suitcase_power_supply_side.jpg :alt: |d-60| power supply showing two |m3| screws going through the anchor |d-60| power supply showing two |m3| screws going through the anchor (side view) .. figure:: /images/modular_suitcase_power_supply_frontal.jpg :alt: |d-60| power supply showing two |m3| screws going through the anchor |d-60| power supply showing two |m3| screws going through the anchor (frontal view) | Putting in all the blind rivets is not so much fun. Therefore the *fun* from before. .. figure:: /images/modular_suitcase_blind_rivet.jpg :alt: Blind rivets: 4,8mm * 10mm (left) and 4,8mm * 15mm (right) Blind rivets: 4,8mm * 10mm (left) and 4,8mm * 15mm (right). Nearly 140 are needed of the latter. | **Note**: You might want to do this in two sessions, depending on what kind of tools you use, otherwise this might seriously hurt your wrists! | **Attention**: The `upper blind rivet on each bottom corner casemaker`_ orthognal to the rail should be a short one (4,8mm x 10mm), so it doesn't interfere with the rail! | | The blind rivets can have an additional washer on the inside of the suitcase. This is not really necessary, but gives some extra stability (and weight), especially in the spots, where there's no metal involved on both sides of the plywood. | .. figure:: /images/modular_suitcase_blind_rivet_washer_inside.jpg :alt: Blind rivets through a corner casemaker with additional washers Blind rivets through a corner casemaker with additional washers and a rail with an edge sawed off. .. _upper blind rivet on each bottom corner casemaker: .. figure:: /images/modular_suitcase_blind_rivet_and_screw_outside.jpg :alt: Blind rivets as they should look like on the outside of the suitcase Blind rivets as they should look like on the outside of the suitcase and a screw holding a rail.
