Combination lock style panel control knob

prusaprinters

<p>Designed for a Creality Ender 3 or similar, that has a 6.25mm knurled shaft that sticks out 12mm from the panel.</p> <p>It's inspired by the combination dial (see remix), but that one's for a much shorter shaft.</p> <p>Designed in OpenScad. Uses the 'Star' library I found at <a href="https://gist.github.com/anoved/9622826">https://gist.github.com/anoved/9622826</a></p> <p>The numbers and slots are highlighted by the rudimentary method of dipping in strong coffee (old coffee grounds mixed with cold water). Works well enough for my purposes.</p> <p>The newer photo is a reprint, where the numbers area is 0.08mm layer height and the rest is 0.16mm. Post-processing is to gently smooth the numbers area even more and rub in some plasticine. It looks much better than the coffee method.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.16</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>15%</p></div><br/> <strong>Filament:</strong><br/> Chinese PLA white <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>I dipped the lower part of the dial in coffee to get some contrast between the numbers and slots, and the top layer.</p></div></p> </p></p></p> Category: 3D Printer Accessories
