12-Piece 3D Puzzle

<p>A delightful little 12-piece 3D puzzle that makes a dodecahedron when solved. Solve it, and you will be rewarded with a fine desk ornament.</p><h3>Printing</h3><p>The <strong>dodecahedron.stl</strong> file contains all 12 pieces in their solved positions. To print, you will need to “Split to objects” and then arrange them with the flat faces down. This is already done for you in the <strong>dodecahedron.3mf</strong> file (make sure to select your own printer and filament, though). I printed this on the Prusa Mini+ in PLA. The Mini is not large enough to print all twelve pieces at once, so I had to disable half of the pieces at a time, and do two separate prints.&nbsp;</p><p>You may need to experiment to get the pieces to fit together well. &nbsp;Depending on your particular printer and filament, you may need to use <i>XY Size Compensation </i>(in the Expert settings on PrusaSlicer) to achieve a good fit between the pieces. Increasing the elephant foot compensation won't hurt either, to make sure there's no additional interference caused by elephant foot.</p><p>Begin by printing just two of the pieces. They should fit together without needing to apply much force. If they fit too tightly, decrease the XY Size Compensation. If they are too loose, increase the XY Size Compensation.</p><p>The <strong>gcode</strong> and <strong>3mf</strong> files were made using the following settings, which worked well for me:</p><ul><li>Prusa Mini+</li><li>Prusament PLA</li><li>0.2 mm layer height</li><li>No supports</li><li>15% infill</li><li>XY Size Compensation = -0.05 mm</li><li>Elephant foot compensation = 0.3 mm</li></ul><p>&nbsp;</p>
