GoPro mount to Garmin quarter-turn adapter for bike lights

A puck that lets a bike light with a GoPro-style two-finger foot, such as a Knog Blinder, Exposure Strada or Magicshine, hang from a spare Garmin quarter-turn socket on an out-front mount. The top carries the male Garmin quarter-turn tab profile with 0.2 mm clearance, the bottom has a GoPro fork: two 3 mm fingers, a 3.2 mm gap and a 5.2 mm hole for the M5 thumbscrew. Overall height is 14 mm so the light sits close to the mount, and it prints with the fingers up in PETG or nylon for toughness.

Adapters like this exist in shops, but never in the exact orientation or height you need, and a loose one lets a 600 lumen light swing. In SpeakCAD you specify the finger count, rotation and height, preview the adapter free in the browser, tweak it in the chat, then download the STL.

Model a Garmin quarter-turn to GoPro adapter puck 14 mm tall with a male Garmin four-tab quarter-turn interface on top, 0.2 mm clearance, and a two-finger GoPro fork below with 3 mm fingers, a 3.2 mm gap and a 5.2 mm through hole.

Change any number to match what you measured. The AI keeps the rest of the design consistent, and small follow-up edits after a download are free.
