I made this to mount a Drift HD Ghost action camera to my bike's forks (BMW S1000R). It should fit any similar forks - around 54mm diameter.
Print it standing up, with supports, and using PETG or similar. Don't use PLA - it will most likely break.
You'll need 5o secure it with an M5 nut and bolt, ideally with a compression washer and/or some threadlock.
