608 Bearing Sleeve for Prusa i3 Spoolmount

This is a sleeve with a beveled end for the 608 bearing. I made this for my printed version of the Prusa i3 spoolmount w/ bearings by sigshoj - http://www.thingiverse.com/thing:590956 . I found that some of my filament spools would not fit perfectly on the bearings, so I made some sleeves to fit over the 608 bearings. I modified the OpenSCAD file to remove the flange on one end, but kept the bevel on the other. This is a Remix of the Parametric idler pulley by whosawhatsis - http://www.thin
