I wanted to come up with a cheap solution (cost see below) for drying and storing used filament spools and to be able to use them as external spools.
Furthermore I wanted to keep track on the drystage to be able to switch the silica gel on time.
The idea is to not modify the box at all, to be able to reuse them if needed in future (no drilling or glue).
The original lid can be just popped out and replaced with the printed part.

I used cheap Sunlu Antistring PLA with the Bambu generic PLA print profile with 0,2 layer height, 2 wall, no support and 15% infill.
The whole lid/cover & rollers set for one filament box prints in 2h 20min and uses 70,7g (PLA)
Two set fit on a 256mm buildplate and prints in 4h 08min.
The lid/cover only prints in 26min and uses 9,66g.
I also added the fusion 360 file, so you can make changes if needed.
Also added following verions of the lid:
Version 2.3
First public release here on makerworld
Version 2.4
I noticed that the tube often slides to deep into the box, so I added a small chamfer and a hole to be able to stick the filament on the upper part back into the box. This makes it way easier to grab the filament from the PFTE tube.
Added alto two pluges in case, the PTFE tube is not needed to cover the holes an keep the box airtight.
Thanks to dynarun for the inital design idea and rollers, which i added to this design. https://makerworld.com/en/models/39426
