You know what's fun? Solving those sliding puzzles, where you have to slide the tiles to get them to the right sequence. You know what's not fun? Scrambling those sliding puzzles after you just solved it.
There are several print-in-place 15 Puzzles out there, but I couldn't find any that solved my issue. I really don't like scrambling them. So I bring you this version of a double sided 15 Puzzle, where you can just flip it over and solve it again! And again. And again. And again. And again…
I've provided three different tolerances for the puzzle, 0.20, 0.25 and 0.30 mm. If you're not sure what your printer can do, there are tolerance tests, made in the shape of a sliding puzzle with only 3 tiles (a 3 Puzzle?).
Print it at 0.2 mm layer height. If you don't have a multi-material unit for printing the number inlays with different colors, forget about the inlays and just do a filament swap at layers 3 (0.6 mm) and again at layer 29 (5.8 mm).
Have fun!
