Escher's Star Puzzle

prusaprinters

<h3>The Idea</h3><p>More than a decade ago I got a wooden star puzzle that was forgotten for years (Source unknown), so I decided to model it in Fusion 360, a software I'm learning for my 3D printer Maker adventure.</p><p>I took a caliper, measured the lengths, added parameters using some trigonometry and digged into this adventure that now I'm now sharing with you.</p><p>The puzzle consists of 6 pieces that form an <a href="https://mathworld.wolfram.com/EschersSolid.html"><strong>Escher's Solid</strong></a> that is part of a <a href="https://mathworld.wolfram.com/RhombicDodecahedronStellations.html"><strong>Rhombic Dodecahedron Stellations</strong></a>.</p><p>At the shops and internet you may find different variations of the wooden star puzzle under multiple names.</p><p>The variation I have includes a feature by cutting the external edge from the body to create a more realistic 3D star.</p><h3>Filament Printing Instructions</h3><p>This model does not require any special printing instructions, although I would advise to:</p><ul><li>Print at 0.2 layer height</li><li>No need for supports</li><li>You can print all pieces at once (same color) or print the pieces with different colors.</li></ul><p>There are two versions of the model, one with big tolerance/clearance and a second one with small tolerance/clearance. The motivation: not all of us have the same quality printers and not all of us have the same printer calibration. Pick the version that suits you.</p><p>I printed using the following settings:</p><ul><li>Original Prusa Mini+</li><li>eSUN PLA+ (6 different colors)</li><li>0.2mm layer height</li><li>Prusa Slicer 2.4.2+Linux-x64-GTK3 using a eSUN PLA+ profile (modified from Generic PLA: 205C instead of 210C for Nozzle Other Layers temperature)</li><li>12% infill and Adaptive Cubic infill pattern.</li></ul><p>Each piece has the following characteristics:</p><ul><li>67.05 x 23.8 x 23.8 mm in size</li><li>Takes 47 min to print</li><li>Uses 3.3mt of filament (9.84 gram)</li></ul><p>Note, you need 6 pieces, therefore multiply by 6 the numbers above.</p><h4>Last Words</h4><ul><li>I hope you like this model and if you like it, please give it a like, it will make my day and will allow me to get a Prusa mug.</li><li>Don't hesitate to post your makes including comments that can improve the model.</li><li>You are kindly invited to follow me to get updated every time I upload a new model.</li></ul><p>And the most important: Happy printing &amp; Greetings from the Galilee.</p>
