Custom designed 9U, 84hp Eurorack case. Designed for TipTop Audio Z-Rrails and μZeus Flying Bus Boards (i.e. not "hard" power bus boards. The design could easily (probably) be modified to include a back or bottom which would allow them).
Drafted with the unbelievably amazing SolveSpace
Laser cut job w/recommended material (~9.5mm birch ply) @ Pololu
