Horizontal Spool Roller w/ Adapter for Saintsmart Spools

This is a horizontal filament spool roller derived from http://www.thingiverse.com/thing:31678. I added a adapter for filament-spools coming from Sainsmart with a spool-hole-diameter of 48mm.

I prefer this horizontal position because the ABS from Sainsmart has a bad winding and the boundary is too short which is leading to cable spaghetti in vertical position.

I like this roller very much because it is working very good and I can use the very cheap ABS filament without spaghetti :-)
