This is a stand for a round humidity meter used for selling on platforms like Amazon. It can be placed in a YASHE grain/dry box, but it should be suitable for most types of dry boxes.

These boxes are a bit opaque, conical, and a bit tall, but they are otherwise very suitable for filament reels.

I bought it on amazon.com.be, but I can't seem to find it on amazon.com. However, the size is...20.3 x 25 x 11.2 centimeters. If needed, I can easily provide a smaller base.

The ring should be clipped into the hole in the base, so you can print it well without support. I tried it with a support first, but it took longer, used more filament, and the result didn't look as clean.
