Two wall mounts for Xiaomi Aqara motion sensors - a corner mount and a flat wall mount.

The corner mount is oversized for the sensor, but I made them this size to be direct replacements for old 433mhz PIRs that where mounted in the corners of my rooms - these use the same wall anchors and cover the spots where the paint is a different colour... :)

The cup the holds the sensor is held in place with a single M3 screw of appropriate length and an M3 nut.
