15 Puzzle – Sliding Tile Fidget Toy Print-in-Place

NEW: Dragon Puzzle!

After designing my Tic-Tac-Toe, I started thinking about what other games to make for my kids. This classic logic puzzle immediately came to mind — I used to play it all the time as a child, so I decided to bring it to life for FDM printing. The rules are simple: shuffle the tiles as much as you can, then try to put them back in order using only one empty space. Easy to learn, hard to master — and a lot of fun. I printed several copies so we can race against each other!

 

No assembly needed: the tiles are already in place when the print is done. The game prints in two parts: the frame with all 15 sliding tiles already inserted and free to move, and a flat cover that simply snaps into the base.

⚠️ INSTRUCTIONS:

1. The textured PEI plate is strongly recommended.
2. Let the plate cool down for 10–15 minutes before removing the print.
3. Once cool, the part releases easily without forcing — which could accidentally push tiles out of their slots.
4. Put the box with tiles face down on the table, apply a thin line of glue along the inner edge of the frame (keep the glue away from the tiles!)
5. Align the base cap on top of the bottom frame, with textured face down, and snap it into the frame with firm pressure

Please do not rescale — tolerances are tuned for this exact size. If you'd like a smaller version, let me know in the comments!
