Printrbot simple Spool Holder Upgrade (Dirty Mix)

I was not fully satisfied with my Printrbot Spool Holder ( https://www.thingiverse.com/thing:355889) because thee spool needed too much force to spin, and a couple of times the filament broke... ruining the current print.

When i walked by some Airsoft Pellets in a Supermarket i had an Idea of a simple Upgrade. I was lazy, so i simply slapped two things together (the bearing and the cone) :-)

There are already Spool holders with bearings like Thing:1564763 http://www.thingiverse.com/thing:1
