My case designed to work with https://github.com/frosty6742/frozen-slimes-v2
I'm using 8mmx8mm push-on-push-off switches such as https://a.co/d/6yBJxXx
Print the brace and mounting jig to keep the switch aligned with the top case hole and glue the brace to the board after soldering to reinforce the switch.
Printed in PLA+ .2mm layer height and 20% gyroid infill, supports recommended for the top case to support the strap edges (I used paint on supports in the middle of the span) but should bridge fine without if printing with PLA.
Case snaps together and should fit tightly, and can be opened easily with a spudger or guitar pick.
Label text added during slicing for for the MMU3, font from https://www.nerdfonts.com
Added a new version of the case with an opening for the usb-c D1 Mini so they can be programmed without opening.
