Designed to hold a YoLink temp and humidity sensor for use in a monotub (mushroom grow tub). Bracket side and back are open to ensure sensor arrays and reset button are unobstructed. 

Sliced in Orca with tree support, branch diameter of 1, branch density of 15%, and tree wall loops of 2. Printed on a Kobra 2 with minimal post-print processing. 

Rev 3 thickened the back and supports to 3mm as I had one break after being in a freezer for a year. The cold likely makes the PETG brittle so will try a slightly beefier design.
