Door sensor or alarm mount

Simple mount for alarm or door sensors. I made this because there wasn't anything out there that fit the door requiring the sensor. Probably useless for most people but sharing it in case someone else can use it for something. Screw holes are 5mm diameter with 10mm diameter countersink. I used 5x40mm screws with countersunk head, something like this: https://www.amazon.com/Countersunk-Machine-Screws-Phillips-Stainless/dp/B0CT4MRQ6Z/ref=sr_1_3?sr=8-3. Should also work fine with double-sided mounting/foam tape. This install shows a Shelly Door/Window 2 WiFi sensor, available from Amazon: https://www.amazon.com/Shelly-Wireless-Measurement-Lightning-Response/dp/B08WK6BV2K.
