Small Raspberry Pi Pico case with built in cable retainer

This case exposes the USB connector and in the other end has an output for a larger cable (fit's a diameter of 5.5mm nicely) and as part fo the case, there is a cable retainer, helps to keep the cable inside the case and not breaking the connections.

I designed this for using it with the https://www.printables.com/model/723123-foot-pedal-switch that I would like to use as a keyboard that only has the button N (I use that for progressing to the next component when hand assembling PCBs)

It's designed to use 4x M3 brass inserts in the bottom part, and 4x M3 x 8mm cap head screws to keep it together
