In relation to the original - added bend to better match stems with higher rise and GoPro mount underneath to make using different accessories possible using M5 bolt + M5 hex nut.
Comes in 2 versions:
- short - sort of v1 - has slightly chunkier part that bolts to the stem, middle rib of GoPro mount is 3.2mm wide that necessitated bolting it tighter and squeezing ribs together (it was hard to keep it in place on rough terrain when tightening it with fingers/stubby knob)
- long version - v2 - middle rib of go pro mount is 3.4mm wide and Wahoo slot is more extended further to the front, as i wanted to have GoPro mounting part to stay as close as possible to the stem/mounting screws, but also needed additional space to charge Wahoo during ultra distance runs.
Update 08/06/25:
Added V3 - elongated GoPro ribs to strenghten potential breakingpoint (it has happened to me with V2 on really rough descend when was carrying 300g of weight on it), reduced hole diameters to 4.5 mm.
Recommend printing on it's side with use of supports to achieve highest strength from filament (3 perimeters). I've printed it in PETG, and used with Olight BFL1800 (200g) with v1 for +50hrs without failure.
Added stubby M5 bolt holders, not sure where i got it but you can find many similar searching for “m5 knob”.
