15 Puzzle - Sliding Number Puzzle

thingiverse

This is a pretty common puzzle. The goal is to mix up the numbers and then arrange them back in order. I have created an all-in-one print-in-place model that works pretty well, but it might take a little bit of working the pieces back and forth to get it to move smoothly. This version also does not have a back so if you push the tiles too hard they can come apart, but it works great if you have it sitting on a desk or just hold each piece on the front and back. The version with all the individual pieces will allow you to print it in multiple colors and use the base that has a back. Once it is assemble it holds together really well and moves freely. It does take a little bit of work to get the last piece in but it can be done.
