Screw Pack Puzzle

Screw Pack is a colorful packing problem. The object is to fit the seven screws flush in the big nut. The pieces have been designed in a misleading way, such that many packing fit partially, but then the last few screws don't fit. This makes it a confusing puzzle, even when the pieces are easy to distinguish by their color. This beautiful puzzle is FDM printed in ABS and then vapor smoothed in acetone. It comes fully assembled. Have fun!
