Magnet backplate for Tuya Zigbee Lightsensor

I bought a Tuya ZigBee Light Sensor Luminance Sensor and wanted to mount it magnetically at the roof of the house. So i designed a new thicker backplate which holds 2 magnets and has the same measures as the orignal one.

This is the link to the luminance sensor: https://de.aliexpress.com/item/1005009745064220.html

printed with white pla layer on bambulab a1 with preset 0.12mm Fine @BBL A1 . No support needed.
