15 Puzzle - Sliding Number Puzzle

thingiverse

This is a popular brain teaser. The objective is to jumble up the numbers and then reorganize them into order. I have developed an all-in-one print-in-place design that functions quite effectively, although it may take some trial and error to get it moving smoothly. This version lacks a back panel, so if you press the tiles too forcefully they can come loose, but it works beautifully when placed on a desk or held from the front and back. The model featuring individual pieces enables you to print it in multiple colors and utilize a base with a sturdy back. Once assembled, it holds together remarkably well and moves effortlessly. However, getting the final piece into place requires some effort, but it is definitely achievable.
