Button Box - SD Puzzle Box

This is a 20 step sequential discovery puzzle box, with a couple of spring loaded elements. There are 21 individual pieces.

All pieces are designed to be printable without supports, however the 4 spring stl files will likely require a well tuned printer to produce. As for layer height, I generally use 0.3mm for most files, but I would recommend a lower height on the spring and rod files for precision. The material used for the springs can also cause issues, I've found the more malleable PLA's work best.

This is also printable at 80% scale which I think has a nice form factor, however the scaled down springs are harder to print, and more fragile.

Once all pieces are printed, you'll find each is designed to fit into the Core piece in only one way. Once combined they also end up blocking other pieces, so that the box needs to be assembled in a unique order. Hopefully this is doable if challenging, please reach out with any questions!
