My take on the case for QuinLed Dig Quad board V2.

You will need 4x small screws (2.5mm x 4-6mm), 4x M3 heat inserts 4.6x4.0m + 4 M3 bolts 6mm.

My goal was to make it printable without any support (most printers will be able to bridge the openings cleanly)

The model is designed for ABS. If you print PLA, you might want to scale it to 99% to align the mounting holes with the board.
