Cassette Tape Wallet

This is a recreation of an idea I had as a teenager but well designed and with no cellotape used. A Cassette tape wallet that has a press down latch at the top and opens up with an overly complcated hinge. There is a major part missing in the actual card holding aspect, I plan to make that out of leather and then attach it to either side and will update the design with the finished photo.

All the parts should have a tolerance that allows free motion when necessary and the other parts fit together so that they click in place. There may be some sanding needed of parts as these a very small so any machine error will cause large effects. But, I've bought a print of it so we'll see how it turns out.

Some parts will need to be printed multiple times:
Cassette Latch x2
Cassette Runner x2
Knuckle Mount Top x6
Knuckle Hinge 1 x2
Knuckle Hinge 2 x2
Knuckle Hinge Centre 1 x1
Knuckle Hinge Centre 2 x1
Cassette Tape Face A x1
Casseette Tape Face B x1

I made a small alteration so that the runners and latches are both on the same face so there would be no possible twisting issues.
