Designed to hold a 70mai Dash Cam 1S, to a Toyota Yaris Hybrid (2016) mirror stock. The mirror stock is 22mm in this car, the design is for 23mm, Fusion360 files are included so you can adjust the dimensions if needed.

Requires an M3 insert and socket-head bolt to clamp down around the mirror.

Print in a heat resistant material due to sun exposure and high temperatures in a car. PLA is a no go, don't even try it. I printed it in PETG and it seems to have lasted over a year now in Dutch weather, outside in the sun. I did have to re-tighten it once after a few weeks because of the material settling.
