Key chain Knot Cross Puzzle, OCC, Three Pieces, Kong Ming Lock

3D model description

Key chain Knot Cross Puzzle, OCC, 15mm x 25 mm x 5mm

The small cross knot puzzle turned out to be appealing for kids. They wanted a key chain for it. Why not? So I made two versions with two levels of tolerance. It makes a great toy as well as an interesting learning object for 3D design.

You could also change the slicing resolution to adjust the tolerance between the pieces. Have fun!
