This is my first pass at an enclosure for the custom-designed battery powered MQTT humidity and temperature sensors I developed.
It's designed to print the case part of the enclosure upright and the lid flat on the print surface.
I printed in MatterHackers PLA with NO supports and it worked just fine on my i3 MK3. I designed the enclosure to use two M3 screws which screw into the side and secure the lid to the case.
