Homebrew Eurorack 2×84 Case

I want this case to be as compact as possible, though I don’t really know quite how this is going to fit together. I’m thinking it should be possible to fold the aluminium sheet so that it clips into the middle screw groove in the top and bottom extrusions of the (captive-nut) racks, thus avoiding any exposed metal edges. If it works, it should also be possible to fold a front and back plate over a base and then hold them in with a small number of screws.

I cut the ends out of plywood with mostly a handsaw, but using an electric jigsaw for the curve (which I drew freehand on the wood since it wasn’t trying to be circular anyway). The curve didn’t quite work out thanks to problems with the saw and clamps, but some work with a flap sander improved things. [2] The racks have countersunk ⌀3·5mm holes at either end, presumably on the basis that minimising protrusion is good. I had to buy some bolts, but couldn’t get 3·5mm so I’ve drilled the holes out to 4mm. Washers and Nylock nuts on the outside.
At this point things are a bit rough; the plywood could use a little filler but the aluminium can just be sanded and primed. Both will be painted. Black, because, black.
I’m also intending to line the wooden parts with aluminium foil. I wasn’t entirely sure but eventually decided to go with a thinner plywood scrap for the base. The front and rear support strips are another offcut of something, cut longitudinally. In practice the plywood I had for the base turned out to be a bit curved so I used a larger offcut for the rear support strip to help straighten it. The ends screw into these, making the assembly quite solid already.
