This is an universal stand for the round hygrometer you can buy from Bambulab, Amazon, Temu …

It fits all angles as the hygrometer itself can bei turnend freely 360° in the round holder and the holder can rotate freely in the stand.

The smaller stand can be screwed using the center hole so this also can be mounted in any angle. So it can be mounted sideways, top, bottom …

The larger stand is for desktop use.

Also you could mount an adhesive tape to the stands.

Should be printed with a higher resolution, I used black BambuLab ABS with 0.12mm HQ
