Filament dry box. Probably the best one.

Could not find a version fitting the boxes i bought, so I made my one myself.

Will handle spools up to 1kg. Absolute maximum width of roll is 64mm. Any wider will not work.

Fits the “YASHE 3.7L” containers. Might fit others aswell, but please do some research before you buy a different box.

Uses 608ZZ bearings, silicagel, a 4mm R1/8" fitting and hygrometers fitting a cutout size of 45x26mm. 

Suggestions where to find the hardware:

It is a good idea to adjust the inner diameter of the rollers by 0.05mm to get a slightly looser fit for the bearing.

Use supports för the hygrometer version of the base.

For best drying results, use the dual silicagel version.
