About this 3D model

This is a mashup from Mini Heavy Duty Printable Filament Spool with Cylinder Bearings (http://www.thingiverse.com/thing:37432, by cymon) and a Gear Bearing (http://www.thingiverse.com/thing:53451, by emmett). I printed with Slic3r with no problems, but if you need to print with different bearing parameters, let me know. Enjoy!
