If you have issues printing other AMS desiccant models like me, this is the easy-to-print model.
With the redesign 45deg instead of the radius corner and thicker wall, you should have no problem printing without a support structure.
The model is compatible with Xiaomi Smart Thermometer 2, model number: LYWSD03MMC.
The meter is separated from the desiccant to avoid wrong readings due to direct surroundings with the desiccant.
STEP files are included, enjoy print.
