Mount for Raspberry Pi 3 on Prusa MK3S.

Mount for hacking - all ports easily accessible. Raspberry Pi 3 powered off printer's 24 volt power supply (via a buck converter). Plenty of room to stack HATs on the Pi. All tucked neatly behind the frame.

The buck converter is a common Chinese model (from more than one vendor on Aliexpress).

Print instructions

Note this is a bit of a challenging print. You want to print with supports, but block supports for the holes.
