About this 3D model

One spool gear bearing to rule them all. Emmett's gear is rad, but printing one for each different spindle diameter can be time and resource consuming. So I made a master bearing, meant to mount on a reclaimed rod from a printer, and customizable collets to fit (http://www.thingiverse.com/thing:75468). All prints were tested and done in makerware on med defaults 10% fill 2 shells .27
