A case for the Tape64 V2 device for the Commodore 64, which emulates a datacorder. You don't need to print the PCB STL file, it was only used as a reference. As it's possible to assemble this PCB slightly differently, you'll need to ensure the edge connector is aligned with the PCB in the same manner as shown in the STL file.

The case is held together using 2 x 3.5 self tapping screws.
