I wanted to make a more portable eurorack modular case on the cheap. Building off of the tip top audio Happy Ending kit, which has the rails, end-brackets, and power supply, I designed some 3d printable end-caps (files here) and cut some acrylic for a nice clear body.

Total cost under $200, most of which is in the power supply module.

A v2 would countersink the nuts coming out of the end-caps.
