Description
This is my design for a slim filament dry box with a ball bearing spool holder.
Each box needs a total of eight 3D printed parts:
The hygrometer holder and the M10 threaded cap are optional.
All can be printed easily with PLA or PETG, a 0.4mm nozzle. No supports are needed.
Other required parts for one box
The optional hygrometer holder is made to fit models with 44mm front diameter and 41mm housing diameter like this one: https://www.amazon.de/dp/B07HK22QB2
To fully seal the end of the PTFE tube, one more M10 preumatic connector is needed for the self-printed M10 threaded cap.
It is recommended to use the jigs for a precise alignment of the holes that need to be drilled into the cereal box.
The box has been tested successfully with spoold from Extrudr, Bambu Lab, SunLu and eSu. From the dimensions I could find, the box is generally to slim for Prusament spools.
I'd be glad to receive some feedback or comments for further improvements.
Why this design?
It takes some inpiration from Werner's version here: https://www.printables.com/model/634289-filament-dry-box-cheap-and-simple – I liked the overall layout and the slim cereal box he suggested to use, however I wanted to have a spool holder with ball bearings for more reliable printing. Besides, I wanted to use silica gel in bags and the slightly nicer round hygrometers.
