This is a stand for a small hygrometer that I got to monitor the humidity where I store my filaments.

This hygrometer is cheap (about $2/ea on AliExpress) and runs on two AG13 batteries.

Check the dimensions of your hygrometer before printing (H 25 mm x W 45 mm x D 14 mm).
I made four prints underneath for an 8mm anti slip round silicone pad.

Quick print, very handy.
