Mihai's DryBox
3D printed filament dry box
An enclosure for one spool of filament featuring desiccant cages and hygrometer for reducing and monitoring moisture on hygroscopic filament. Rewind system with locking mechanism for when the spool is not in use. Check out the videos!
Make sure to check the advantages and disadvantages first, and follow instructions on the project page.
Printing:
- Print one base (filename starting with "print one base.")
- Print one lid (filename starting with "print one lid.")
- Print all 40 shared files (some are identical)
DXF files included for laser cutting windows.
See the BOM list for required parts.

Can u pls give a list of the bearings and screw sizes and the hydrometer, and the gasket suze
augh! So sorry I wasted my filament to print this. There are no decent instructions and the YouTube video is just a joke!
Excellent box! Worked on first print and keeps humidity at <10%
How about one with the hygrometer on the side but still have a window?
Printed one box already and its pretty awesome actually. Looking to print more but I am struggling to source the gasket to be as air tight as possible. I don't suppose you have had a chance to model a TPU option for it yet?
You need to increase the bedsize in your cura or whatever to 225x225 than it works. with my sprite extruder i had to go with 228x228 and move the thing -2mm in X.
how do you do that?
do you have the original design of the lock for the dry box, i printed the one that is here but is to big and it doesn't fit in my project, can you publicate the version that you have shown in the old video?
Hi , great project.. just one question , did you use 'supports' in your slicer when printing the base with 'windows'? as i will use a 0.6mm nozzle for approx 15hrs of print. Many thanks..
I designed a jig to speed up cutting the window panels: https://thangs.com/mythangs/file/414688
Thanks a lot for sharing this Mihai, much appreciated. Printing it now, 34 hours remaining on the the base.
Edit: I was wondering: have you tried the molecular sieve desiccant yet? Didn't know it existed and very interested. PS for anyone interested too in EU: https://www.amazon.nl/NRC-Moleculaire-zeef-1-liter/dp/B07WV38GGF
