<p>The Problem Solvers Fender Flute (<a href="http://problemsolversbike.com/products/fender_flute">http://problemsolversbike.com/products/fender_flute</a>), optimized for 3D printing.</p> <p>Features 8 holes, spaced 10 mm apart.</p> <p>There are two versions - one for 1-1/8" steerer tubes, &amp; one for 1" steerer tubes.</p> <h3>How I Designed This</h3> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/98/17/29/05/b4/FE0900-390x390.png"/></p> <div><p><a href="http://problemsolversbike.com/products/fender_flute" rel="nofollow">http://problemsolversbike.com/products/fender_flute</a></p> Since it's 3D printed &amp; I couldn't design M6 threads in this piece, I used an inset in the back to hold an M6 locknut (9.91 mm across, uses a 10 mm wrench to tighten). It's designed to hold about half of the flat height, which comes out to be 2.69 mm. <p>I copied the 100 mm length &amp; number of holes (8), but I didn't adhere to the 10 mm thickness &amp; 20 mm width. Instead, I made it 7.5 mm thick.</p> <p>It turns out that the ID of the steerer is 1/8" smaller than its OD (1", 1-1/8") in both cases, for which I've designed (<a href="http://www.retrobike.co.uk/forum/viewtopic.php?t=207027">http://www.retrobike.co.uk/forum/viewtopic.php?t=207027</a>).</p> <h3>Assembly &amp; Materials</h3> <ul> <li>x2 M6 bolts</li> <li>x2 M6 nuts or locknuts</li> </ul> <p>The assembly is pretty self-explanatory once you see the source image.</p> <h3>Future</h3> <p><strong>Stuff I might do in the future, though probably not</strong></p> <p>I was thinking, why even have discrete positions &amp; just have a long slot? Then I remembered that front fenders have a slot anyways. It'd probably be fine with just 1 long slot + front fender slot, but oh well. Maybe I'll do that someday.</p> <p>Also, this would be a cool project to parameterize/customize according to the length you need. Maybe I'll do that someday too.</p> <h3>Updates</h3> <p>2 Feb 17 If you're looking at this &amp; thinking, "that looks a lot like a drop bolt for brakes," 1) you'd be right &amp; 2) do NOT use it as such. It will break instantly under the massive torque of trying to stop any appreciably sized wheel spinning at any appreciable angular velocity.</p> <p><a href="http://www.sheldonbrown.com/home-drop.html">http://www.sheldonbrown.com/home-drop.html</a></p> <p>Do yourself a favor &amp; use something like these:</p> <ul> <li><a href="http://handsonbike.blogspot.com/2013/09/journey-of-boardwalk-part-31-elosix.html">http://handsonbike.blogspot.com/2013/09/journey-of-boardwalk-part-31-elosix.html</a></li> <li><a href="https://www.lfgss.com/conversations/214032/">https://www.lfgss.com/conversations/214032/</a></li> </ul> </div> Category: Replacement Parts
