I’ve noticed that there are some custom back shells for the PicoCalc which are 3D printed that give easy access to the Pico and GPIO Pins.

I do not have a 3D printer that I can print the shell myself, so are there any sites that sell these custom back shells?

Also lots of local libraries in the US have 3d printers.. Not sure where you are but it cant hurt to check their websites or call.
