Smooth Feeding, Dry Filament: Dry Box Spool Holder

I was looking for quite some time to find a solution of an inexpensive good quality dry box fitting my filament spools and offering smooth rotation and easy replacement of spools. 

Long story short I ended up remixing a few designs. Now, I am really happy with this solution and I would like to share it with you. 

Thanks to all the original designs!

==================

Tested Spools: 

• 300g - 1000g
• max. 70mm x 202mm 
• PolyTerra, Creality, Purefil, Bambulab, azure film

Assembly Guide: 

1. Connect the screw with the nut
2. Add the bearing holder and the bearings
3. Add the bearing cap and glue it
4. Use the mount guide to markt the drill holes
5. Drill the holes
6. Attach the screw mount in and outside with M3x(6-10mm) with hex nuts
