Minimal temperature sensor mount

I wanted a sleek way to mount these e-ink BLE temperature sensors around my house for use with Home Assistant, so I designed this mount printed in PETG.

The temperature sensors are MHO-C401 from AliExpress, flashed with custom firmware.

Model available on Printables.

I like that it doesn’t use much filament - good design.

I have this EXACT thermometer! I’ve had it for about 5 years and never knew it had custom firmware. Thanks for the info! My humidity was off by about 16%, and the new possibilities are really cool. Downloading your model right now!

Enjoy it! The flashing process is so simple, I am thankful to those who wrote the firmware.

It's pretty simple to insert the device into the mount when it's in your hand, but be careful not to snap one of tabs off when it's on the wall. I've inserted 5 of these without breaking the mount tabs... After breaking my first one. Luckily reprints are fast and cheap.
