Steerer tube mount for Wahoo Elemnt Bolt

thingiverse

I recently picked up a Wahoo Elemnt Bolt to replace an old Garmin Edge 500, and discovered that the mount looks like a Garmin mount but is actually rotated 90 degrees. I had been using Bryce's Garmin stem mount and he kindly adjusted it for me, but the dimensions are slightly off, so the fit on the Wahoo was quite tight... so I ended up redesigning it. I also saw a request for a Wahoo mount that's compatible with the Bontrager Blendr mount, so I used this basic mount design to work with both of them, steerer tube and Blendr mount. This one is the steerer-tube mount, which replaces a standard 1 1/8" headset spacer to mount the Wahoo over the stem. I've also included one that replaces the stem cap and a spacer, requiring a flat head M6 screw in the range of 25-35 mm. The flat head distributes 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. **Warning!** 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 sticking with a conventional aluminum top cap is probably a better idea. I've printed this out (with a standard aluminum top cap) and have been using it with great results on my trail bike.
