Since I don't have the matching GoPro adapter to attach my bicycle headlight to the new "cockpit", I designed this simple adapter that screws to the underside of the bike computer mount, similar to the included action-cam adapter.

It should be printed in a tough material, with quite a few perimeters and not too sparse infill. I've used PETG, with four perimeters and 25% infill.

I've included two versions of the mount (as STEP files): one with an integrated modifier part and one without. The intention of this modifier is to print this section of the model with only two perimeters, thereby making the bridging a little cleaner.

Setup in PrusaSlicer

  1. Load Microbar_for_ZTTO_cockpit-mount.step (the version with the modifier).


     
  2. Rotate it 180°.


     
  3. Chage the type of the modifier body …


     
  4. … to “Modifier”.


     
  5. Klick the gear icon and select Layers and Perimeters.


     
  6. Finally, change the number of perimeters to two.

PS: FreeCAD source file included! 🙂
