Parametric headset spacers for bicycle threadless headsets

<p><strong>Update 9 Jan 2020:</strong> Thanks to <a href="/zachariazh/about">zachariazh</a> for pointing out that you can pay nearly 20€ for what is basically the <a href="https://www.extralite.com/imagesbike/ExtraBolt/Eb103dp.jpg">same exact thing</a> from <a href="https://www.extralite.com/Products/ExtraBolts_anglo.htm">Extralite</a>, the Italian manufacturer of super lightweight weight weenie parts. The only thing you don't get with my design is the "Extralite" logo printed on the side. Considering their scale photos compared to mine, I thought about putting an "Extraliter" logo on mine but that might be a bit much.</p> <p>Plenty of headset spacers here on Thingiverse, probably because a headset spacer is basically a simple hollow cylinder. Not the most complicated design.</p> <p>What makes mine different? Not a whole bunch, but I do have several varieties available along with the basic simple spacer:</p> <ul> <li>Hourglass spacer<br/> Thicker at the ends, thinner in the middle. Results in the lightest spacer which is perfect for the weight weenies amongst us.</li> <li>Rounded hourglass spacer<br/> As above, narrower in the center, but takes a nice smooth curve from top to bottom.</li> <li>Internally butted spacer<br/> Similar to the hourglass spacer, but the butting happens on the inside. Looks more conventional from the outside but is still ridiculously light</li> <li>S-Works clone spacer<br/> A clone of the carbon fiber spacers that came on my Epic that has a simple splined design.</li> <li><p>Simple straight spacer<br/> Because why not?<br/> The design is parametric, if you import the F3D file into Fusion 360, you can go under Modify and choose "Change Parameters" and update any of the user parameters to regenerate all the spacers. The best approach here is to know how many spacers you need and print one spacer of the appropriate height, vs stacking spacers to get that height.</p> <p>Two other cool designs:</p> </li> <li><p>T70E's cool "wave" headset spacers: <a href="https://www.thingiverse.com/thing:2514543">https://www.thingiverse.com/thing:2514543</a></p> </li> <li>FooFighter's adjustable headset spacers: <a href="https://www.thingiverse.com/thing:1640992">https://www.thingiverse.com/thing:1640992</a></li> </ul> <h3>Print instructions</h3><h3>Category: Sport &amp; Outdoors Summary</h3> <p><strong>Update 9 Jan 2020:</strong> Thanks to <a href="/zachariazh/about">zachariazh</a> for pointing out that you can pay nearly 20€ for what is basically the <a href="https://www.extralite.com/imagesbike/ExtraBolt/Eb103dp.jpg">same exact thing</a> from <a href="https://www.extralite.com/Products/ExtraBolts_anglo.htm">Extralite</a>, the Italian manufacturer of super lightweight weight weenie parts.
