About this 3D model
This version is an improvement based on the version by B station UP: @忙了一天的高师傅. The original author's version is for Xiaomi Bluetooth temperature and humidity sensor, with a charging port at the bottom. It uses 8 N52 small round magnets with a size of 6x2 for magnetic adsorption. It can be placed inside a drying box or used on a printer enclosure. I have modified the size to fit a cheap button battery temperature and humidity sensor. You can use the provided pictures to purchase a temperature and humidity sensor and print the bracket. PLA/PETG can be used for printing.
