This is a stand for a round digital hygrometer with temperature sensor. I bought some of these for my filament dry boxes. With this stand, the unit can also be used to measure the room humidity on some more attractive way. It's a cheap but quite accurate device that can be bought from Ama-zon and Ali-Express.

New: A user reports wrong orientation due to product deviation. Or perhaps there are different types of these hygrometers on the market. For those who have this problem with the original hygrometer stand, a hygrometer stand has been added where the end position is adjustable 3 degree clock and counterclockwise compared to the original hygrometer stand.

Print settings: 0.4 nozzle 0.20 or less layer height 100% infill I used PETG filament, but any other stiff filament can also be used.

Cura setting for a smooth round outer surface: Z Seam Alignment position: Front
