9-wheel Kryptex

prusaprinters

<p>This <strong>KRYPTEX</strong> is a longer variant of Hiob's 6-wheel cryptex. With a billion possible combinations as opposed to a million, it's a bit harder to crack. Hence the unambiguously hard K instead of a C in the name. ;-)</p><p>Hiob's design is based on <a href="https://www.thingiverse.com/thing:651654">CloudJ's design</a>, which is nicely <a href="https://www.youtube.com/watch?v=7VVoWhzlGwM">demonstrated on YouTube</a>.</p><h3>Print Settings</h3><p><strong>Rafts: </strong>No</p><p><strong>Supports: </strong>No</p><p><strong>Resolution: </strong>0.1mm for outer rings, 0.3mm for all other parts</p><p><strong>Infill: </strong>100%</p><p><strong>Filament: </strong>PLA Brown, Gray, &amp; Black</p><p><strong>Bottom &amp; top fill:</strong> Archimedian Chords</p><p><strong>Perimeters</strong>: 1</p><p>Print nine outer wheels. Print one of every other piece. See which size of inner wheel fits best, then print eight more of that size.</p><h3>How I Designed This</h3><p>I extended parts A and B of Hiob's cryptex design by 36.6 mm to accommodate 3 more discs.</p><h3>Filament Selection &amp; Finishing Touches</h3><p>I selected the following materials:</p><ul><li>ColorFabb™ steelFill™ filament for the decagonal endpieces of parts A and B; black PLA for the cylindrical sections</li><li>Dark brown PLA for inner wheels</li><li>Cherry wood PLA for outer wheels</li></ul><p>I sanded the steel- and wood-infused parts a bit and brushed them with steel wool. This improved the appearance and lightened the color of non-recessed areas so that numerals and index marks stand out. I sanded the sides of the assembled wheels a little till they all turned easily.</p>
