Tightener Knob for Square Jellyfish Tripod Mount

prusaprinters

<p><strong>10.10.22 Update:</strong> Added a second version were the nut in inserted to the print part way. This avoid any gluing and results in a clear print. It also had chambered edges to make tightening less painful.</p><p>&nbsp;</p><p>I have used the <a href="https://squarejellyfish.com/tablet-tripod-mount-details/">Mini Tablet Tripod Mount</a> from <a href="https://squarejellyfish.com/">Square Jellyfish</a> for several years and been really happy with it. Last week after a camping trip, I lost the screw knob that tightens the mount (see image below).&nbsp;</p><p>Went to Home Depot and picked up a couple M4-0.7mm Hex Nut for $2 and modeled a new parametric knob in <a href="https://cad.onshape.com/documents/07632c54f79a26981c39955b/w/05aa59fa4c8d1ac965aaebe8/e/aed64dbe283f1897a2222a74">OnShape</a> based on my memory and reference pictures I found online. A small dollup of super glue to secure the nut and I'm back in business.</p><p><i><strong>WARNING: If using glue, make sure to use a small amount of super glue otherwise you risk getting it in the threads of the hex nut.&nbsp;</strong></i></p><p><img class="image_resized" style="width:50%;" src="https://media.printables.com/media/prints/292572/rich_content/c5923b1d-2427-4bde-b69c-d31c5880a06a/missing-knob.jpg#%7B%22uuid%22%3A%2210260dcf-7493-4200-a9df-4935b6f8c3ab%22%2C%22w%22%3A1280%2C%22h%22%3A960%7D"><img class="image_resized" style="width:50%;" src="https://media.printables.com/media/prints/292572/rich_content/04346cdf-f164-466b-84c6-1fdfe8566047/reference-knob.jpg#%7B%22uuid%22%3A%2250fb6191-5fca-4b3d-a3f0-4198dc2dfe19%22%2C%22w%22%3A1280%2C%22h%22%3A960%7D"></p><p>&nbsp;</p><figure class="table"><table><thead><tr><th colspan="2"><h3>Print Settings</h3></th></tr></thead><tbody><tr><td>Printer</td><td>Prusa Mini+</td></tr><tr><td>Brim</td><td>No</td></tr><tr><td>Supports</td><td>No</td></tr><tr><td>Nozzle</td><td>0.6mm Brass</td></tr><tr><td>Resolution</td><td>0.40mm DRAFT</td></tr><tr><td>Infill</td><td>100%</td></tr><tr><td>Perimeters</td><td>3 <i>(for added strength)</i></td></tr><tr><td>Filament</td><td><a href="https://www.microcenter.com/product/611542/inland-175mm-red-pla-3d-printer-filament-1kg-spool-(22-lbs)">Inland 1.75mm Red PLA+</a></td></tr></tbody></table></figure><p>&nbsp;</p><figure class="table"><table><thead><tr><th colspan="3"><h3>Assembly: Materials &amp; Tools</h3></th></tr></thead><tbody><tr><td>Hex Nut</td><td>$2</td><td><a href="https://www.homedepot.com/p/4-mm-0-7-Stainless-Steel-Metric-Hex-Nut-2-per-Pack-800998/204274078">M4 - 0.7 Stainless Steel Metric Hex Nut (2 per Pack)</a></td></tr><tr><td>Super Glue</td><td>$6</td><td><a href="https://www.gorillatough.com/product/gorilla-super-glue-gel/">Gorilla Super Glue Gel</a></td></tr></tbody></table></figure>
