Steerer tube mount for Wahoo Elemnt Bolt

prusaprinters

<p>I recently got a Wahoo Elemnt Bolt to replace an old and quirky Garmin Edge 500, and discovered that although the mount<em>looks</em> like a Garmin mount, it's rotated 90 degrees. I had been using Bryce's <a href="https://www.thingiverse.com/thing:2865968">Garmin stem mount</a> and he was nice enough to rotate the mount for me, but the dimensions are also slightly different so the fit on the Wahoo was quite tight... so I wound up redesigning it. I had also seen a request for a <a href="https://www.thingiverse.com/thing:3348826">Wahoo mount that is compatible with the Bontrager Blendr mount</a>, so I used this basic mount design to work with both of the designs, steerer tube and Blendr mount. This one is the steerer-tube mount, it replaces a standard 1 1/8" headset spacer to mount the Wahoo over the stem.</p> <p>I've also included one that replaces the stem cap and a spacer. It requires a flat head M6 screw in the range of 25-35 mm. The flat head will distribute stress through the cap more evenly, whereas a standard socket head would concentrate all the stress on one layer boundary and make the cap more likely to break.<strong>Warning!</strong> I printed one in PETG and when I used it on my bike, it didn't break, but the whole curved top cap surface just kinda sank down. I think staying with a conventional aluminum top cap is probably a better idea.</p> <p>I've printed this out (with a standard aluminum top cap) and have been using it with great results on my trail bike.</p> <h3>Print instructions</h3><h3>Category: Sport &amp; Outdoors Summary</h3> <p>I recently got a Wahoo Elemnt Bolt to replace an old and quirky Garmin Edge 500, and discovered that although the mount<em>looks</em> like a Garmin mount, it's rotated 90 degrees.
