3D printing the parts
Download and print the 3D models from the official repository:
Commodore PET Mini files
There are eight pieces to print, provided in individual STL files ready to be sliced. Each piece is oriented to optimize printing quality and minimize the risk of a failed print as much as possible. I recommend you to keep this orientation and to add supports when slicing. Also, don't forget to choose the right plastic color for each piece:
Base
Body shell
Keyboard
Monitor stand
Monitor box body
Monitor box rear cap
Monitor box front
Monitor frame
