Simple ring to hold and view Humidistat for stored filament spools
thingiverse
Simple ring to hold and center a cheap (~$3) Humidistat in the center of a ring while storing in a vacuum storage bag. I then cut a round hole in the cardboard filament box and tape it over with clear packing tape to create a window that allows me to read the humidity without opening the box. Update (7/11/2022): Added a version with channels to allow for more communication of air & humidity between center and spool itself.
