I wanted to print a portable eurorack case that could could be powered via a USB power bank and played on the go, so here's my 38HP travel skiff! I utilized the rotated 4HP 3U for power, multiple, and mute modules.
No supports needed, but you'll have to turn off skirts if printing on a Prusa Mini. I've uploaded two different case depths (correlate to module depth, not lower case height), comment if you'd like a different one. Top lid has 9 holes to screw into the lower case. All holes are slightly undersized so you should be able to screw in modules with 3mm screws like normal. Handle and washers were sized for different screws and may need to be modified.
Here are some power solutions! I'm using an Endorphin Power module with a USB Type C 3.1 PD to 5.5mm Barrel Jack 15V 5A Cable from https://www.adafruit.com/product/5451
You could also use a power supply like Uzeus or if you want to power it via USB Type B you could try the MMI Modular USB Power.
