Cylinder 15 puzzle

cults3d

This is akin to solving those classic sliding-tile 15 puzzles, but on a cylindrical surface with periodic boundary conditions. Think of it as a 23-puzzle instead. To begin, you need to print out the spool's bottom, top, and intermediate section - what we'll refer to as the spacer. Additionally, you must print out the puzzle pieces themselves, which are named piece__stl, where X and Y denote their designated positions on the grid. Assembly Instructions: Firstly, place all the tiles around the bottom part of the spool. You may need to manually hold them in place until it's fully assembled. Next, position the spacer atop the spool's base, followed by screwing the spool top onto the bottom section with the spacer serving as a buffer. The tabs on each puzzle piece should fit snugly into the circular slot along the spool top. If the assembly appears too tight or loose from top to bottom, you can easily reprint a spacer of varying height to achieve the desired balance.
