Having found nothing to print for this 4-in-1 tape emulator for the Commodore 64, I decided to design it
It is recommended to use at least 50% infill
With a 2mm drill bit, make holes on the sides of the board as you can see from the photos... don't worry, they don't cause damage as no contacts pass through that area, then get 2 suitable small screws to fix the board to the base, I used 2 small screws about 2mm that I recovered, for the lid I used 4 self-tapping screws about 3mm thick

Obviously, I do not assume any responsibility for damages of any kind caused
