This is an enclosure for an MT32 Pi using a Pi Zero 2W and the MT32 Pi Hat sold by Yavimaya Maker at:
https://www.tindie.com/products/taviens/mt32pi-hat-for-zero-2w-model-raspberry-pi/
It uses 4x M2.5 20mm countersunk screws to attach the front to the back. (or 22mm if you want some extra security)
It's relatively thin so the ports can be easily accessed, with plenty of ventilation. The lip between the front and back is split to make it easy to get the pi in and out of the case.
I also included a back that has a mounting bracket for The Brigandier's MiSTer Pi case 'cause I wanted one.
Edit: It was requested that I add one with holes spaced for more typical cases, where the panels go straight into the board standoffs… so I've added that as well.
You'll need at least 2 spacers for the side without the connector, but you can use 4 if you want some extra security.
Getting the switch cap to settle onto the switch might be a bit tricky depending on your printer's tolerances.
The microSD card is a little tricky to get at, but if your fingernails are too short, just about any small tool should be able to pry it out. (you could even use the usb cable angled in just right)
