Universal GoPro mount for cars. Originally designed to fit Toyota GR86 or other cars with headrest with 14mm diameter pins spaced 135mm center to center, but have since then also added a version with 150mm spacing that is supposed to fit earlier GT86/FR-S and BRZ cars. Uses M5 screws (standard GoPro screws can be used) to clamp onto the headrest pins.

I printed in PLA (for stiffness) and without support.
