Kobra S1 Dry Rear Spool Holder

I am a lazy person and do not like to put my filament back into its bag when I am done printing. This malicious behaviour leads to wet spools, which I also do not like.

My laziness cannot be fixed, but this does help with the filament at least.to mount it, you can just use the rear spool holder screw holes with ~9mm M3It works well but i call it a prototype because i am not completely happy with the simple appearance and would like to add more mechanical features in the future. 

-Fits common Sizes, up to 220x80mm Spools.-The little hole on the side should fit the bowden tube perfectly. -The threading allows quick removal of the drum. -My print went a little weird on the outer chamfer as you might see in the picture so i made it steeper for easier printing. -I also corrected the handle floating in the middle outer hole which did not change much since the drum also sits in the middle of the screw handle. -There is no compartment for silica gel yet.
