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
- Load
Microbar_for_ZTTO_cockpit-mount.step(the version with the modifier).
- Rotate it 180°.

- Chage the type of the
modifierbody …
- … to “Modifier”.

- Klick the gear icon and select
Layers and Perimeters.
- Finally, change the number of perimeters to two.
