Bontrager Pro Ion to GoPro Adapter
thingiverse
Bontrager to GoPro mounting adapter. Inspired by Bould170's adapter. Opted for an over-the-center cam lever instead of the press tab. The cam provides reasonable clamping pressure but it's not invincible. It was a tradeoff between clamping pressure and deflection of the adapter. Fusion 360 file included for your convenience.
