Description
Just finished building the Printrbot Small Tower. The Toy Builder spool was just a bit too narrow to fit on the skate rollers. Replaced the bearings with this roller instead. Frankly it's so smooth that it doesn't need to roll. The spool slides over the rollers.
Form an idea by my Padawn. Awesome job. OpenScad source included.

And an additional idea by MrChristo: Feed the floss from the bottom, under the front roller. Appears to be less stress.
Also, print the Roller Extenders: http://www.thingiverse.com/thing:302483 to complete the set. Accommodates wider rolls!
