Hammerhead Karoo 2 out-front mount with GoPro underside
The Hammerhead Karoo 2 is a big unit at 100.6 x 60.8 x 19.3 mm and needs an arm long enough to clear the stem faceplate. This out-front mount clamps a 31.8 mm bar, reaches 85 mm forward and ends in a quarter-turn socket matching the Karoo's Garmin-style tabs, with a three-finger GoPro interface underneath (3 mm fingers, 3.2 mm gaps, M5 thumbscrew hole) for a Varia UT800, Exposure or Knog front light. The arm is 10 mm thick and 22 mm wide with a 2 mm skin over honeycomb infill, and it prints upside down on the head face in PETG.
A measured mount keeps the heavy Karoo from sagging and puts the light exactly where the fork does not shadow it. Describe your clamp size, reach and light position in SpeakCAD, preview the model free in the browser, refine it in the chat, then download the STL or 3MF.
