I made a case for Raspberry Pi Pico. There's also a hole for the BOOTSEL button. Designed this case to be used as usb with a micro USB male - USB-A male adaptor (photo) and make it a "rubber ducky bad usb" according to this guide https://github.com/dbisu/pico-ducky. No supports needed, just remember to rotate the thing in your favourite slicer program so the base looks down.
