A simple mount for securing a ThermoPro TP50 hygrometer/thermometer in a filament dry box.

My original intent was to design a mounting bracket that permitted me to easily remove the hygrometer without tools, yet holds the unit securely. When a single bracket is used in a vertical orientation, it suits that requirement quite nicely.

For a more secure mounting option, such as for mounting horizontally under a top cover, you can also use two brackets (one each for the top and bottom) and still easily gain access to the battery compartment and buttons on the back of the unit.

Required hardware for a single bracket installation:

2 - M3 x 10 bolt (any length between 8mm and 12mm should be fine)
2 - M3 nut
2 - M3 washer

UPDATE 2019/04/08 The original version of this was made using Microsoft 3D Builder. To simplify modification, I've recreated it as a parametric design in Fusion 360. The STL files prefixed with F360 represent the new version, and the Fusion 360 export archive (F3D) is included for anyone who wishes to modify measurements to suit their purposes. I have not performed a test print myself, but it is based on the same measurements and should be identical to the originals.
