This ThirdReality R1 motion sensor mount is designed to let you position the sensor exactly as you like.

It features a GoPro-style mounting system with two axes, allowing both vertical and horizontal adjustment.

The assembly uses two M5 hex nuts and two M5x20 bolts.

In the provided .3mf file, you’ll find three parts: the sensor holder, the wall/ceiling mount, and the central mounting piece.

Print the sensor holder and the central mounting piece with 30% infill, while the wall/ceiling mount should be printed at 100% infill for the required strength.

The wall/ceiling mount has four M4 holes, though these aren’t strictly necessary, I personally used double-sided 3M tape to secure my sensor to the wall.
