Made this model so that the new filament spools that come on cardboard spools roll off better of the spool holder.

Outer Diameter is 53 mm so it fits the standard cardboardspool. (Tested with Jayo and eSun cardboardspool)

Inner diameter is 42 mm fits over most of the standard or custom filament holders. I especially made it so it fits better on this custom filament holder i made: https://www.printables.com/model/126420-anycubic-vyper-filament-spool-holder-with-bearings 

Width is adjustable from 50mm to 65 mm (more is poosible, but than you don't have clean inner surface, but I don't think that you need that much for a normal spool anyway.)

You need to print two seperate objects so that you can screw them together and reuse it with all your other spools. 

I printed it with PLA+ (eSun olive green)

0,2 Layer Height works perfectly
