A simple hygrometer mount for filament when stored in vacuum-sealed bags.
I was looking for a good way to see the humidity of stored filament when on it's side that works with slightly different sizes of 1KG spools. I store mine all side-by-side so this saves me from wondering if I need to dry the filament!
- Bumpers are printed in TPU
- Should accommodate most standard-size spools, from about 55-62mm wide.
Hygrometers used:
- I purchased a multi-pack of cheap hygrometers from Amazon; there are many different ones for sale that appear to be the identical design to what I got.
- If you can't find these, here are a few ASIN#s for Amazon products that look to be identical:
- B0CGHRMGVV
- B08P3QJJZL
Hardware I used:
- 4pcs M3x10mm screws
- 4pcs M3 Nuts
Printing:
- I used supports for the case body when printing; found that organic supports were the easiest to clean up in PrusaSlicer.

- I use indicating silica gel in an organza bag to keep things tidy.

Happy printing!
