Remix of the excellent cereal box spool holder model by OdinStampe3D modified to hold a Xiaomi thermometer/hygrometer, model LYWSD03MMC. Designed and printed from the PLA profile of the original, not sure how it'll do with other materials.
I recommend flashing custom firmware onto the hygrometer to extend battery life and also allow easy integration with Home Assistant w/ BTHome: https://github.com/pvvx/ATC_MiThermometer
The author remixed this model.
