Simple square humidity gauge holder

This is a really simple design to hold this humidity gauge inside a storage bin. Ive added support for the bridges and a brim in my print profile for safty, but that should work fine without any. Will work with any screw with diameter of 4mm or less (you'll need the screw nut size according to the screw you use), i'm using 6-32 12mm long screws, but classic m3 will work! Have the round one? also available here!
