<p>Update 21 APR 2019</p> <p>There is a newer easier-to-print version of this puzzle at <a href="https://www.thingiverse.com/thing:3578594">https://www.thingiverse.com/thing:3578594</a>.</p> <p>This puzzle was my entry for the 2011 IPP Puzzle Design competition in Berlin where it was a Jury 1st Prize winner.</p> <p>"Two open-ended Superstrings with the correct spin can be merged into a super-symmetrical cube."</p> <p>The idea for this puzzle emerged when I was designing shapes based on two interlocked tetrahedra. Inspired by ideas from 'string theory' and 'super-symmetry', I began to search for shapes that were both symmetrical and as similar as possible.</p> <p>The two pieces may look similar but they are very slightly different.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Mendel90</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2 mm</p></div> <p><strong>Infill:</strong></p> <p>30</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>The competition entry was printed in nylon by Shapeways and is still available to purchase on their site - <a href="https://www.shapeways.com/product/79EZ8M87R/superstrings" rel="nofollow">https://www.shapeways.com/product/79EZ8M87R/superstrings</a>.<br/> With good support material settings it is also possible to print this on an FDM printer at home. <h3>Post-Printing</h3> <p>Taking the two pieces apart is not too difficult; reassembling them back into a cube can be more challenging. Hold one of the pieces still; move the other piece through the correct sequence of lateral and rotational moves.</p> <p>The solution document can be found in ThingFiles.</p> </p></div></p></p> Category: Puzzles
