Raspberry Pi Compute Module 4 with Waveshare nano b / a CM4 case

A small case to enclose a raspberry pi compute module with a waveshare nano b board with space to allow for a heat sink.

EDIT: Requested, nano A has been added. I do not have the board myself, so feedback welcomed.

The idea was to be simplistic and print with 1 model and have access to all ports.

To insert, start with the ethernet port angled down towards the bottom and insert at that angle, then with a little pressure slide the USB/hdmi side down. It is only a little snug, with a tang on the USB side to hold in place.
