Stem Cap Light Mount

prusaprinters

<p>Gain another mounting location for a light or bike computer by replacing your bicycle's stem cap with this part. The mounting tube is 31.8mm - the same size as many modern bicycle handlebars.</p> <p>Similar to <a href="https://www.paulcomp.com/shop/components/mounting-solutions/light-mounts/stem-cap-light-mount/">Paul's Stem Cap Light Mount</a>, but this one can be made on a 3D printer.</p> <p>Note that, this part will never be as bombproof as a Paul's part machined out of aluminum. This design was inspired by the Paul's part, but not a copy of it. However, this is an alternative that you can use to test fitment. If your light is not too heavy, it might work for you.</p> <p>You can customize the design by checking it out:<br/> <a href="https://github.com/thrasher/stem-cap-light-mount">https://github.com/thrasher/stem-cap-light-mount</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div><strong>Resolution:</strong></p> <p>0.1mm</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>25%</p></div><br/> <strong>Filament:</strong><br/> Prusa ABS/ASA or PLA <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Print with at least 25% infill, with 3 shells, for strength.</p> Orient the part with the flat side surface on the print bed.<br/> Supports on the bed are required in this position.</div></p> <p>Print with ABS or ASA for UV protection. If you print with PLA, paint the part with a UV resistant paint to protect it.</p> <h3> Post-Printing</h3> <p><strong>Installation</strong></p> <p>Stem caps on threadless bicycle stems are used to properly load the headset. This plastic part is not strong enough to do that, but can still be used:</p> <ol> <li>Use the original stem cap to adjust the headset load</li> <li>Tighten the stem's clamp bolts to the proper torque</li> <li>Remove (and save) the original stem cap</li> <li><p>Install this one, using the original bolt, but tighten it just enough to hold (not as much as required for stem cap adjustment)</p> <h3>How I Designed This</h3> <p>All code to create the part is found here:</p> <p><a href="https://github.com/thrasher/stem-cap-light-mount">https://github.com/thrasher/stem-cap-light-mount</a></p> <p>The fillets between the parts were made using the excellent <a href="http://www.scorchworks.com/Blog/openscad-modules-for-automatic-fillets-and-radii/">Fillets and Round code by Scorch</a>. Unfortunately, they take a long time to render, so are disabled in OpenSCAD's preview mode. Use the render.py script to render for printing if needed.</p> </li> </ol> </p></p></p> Category: Sport &amp; Outdoors
