About this 3D model
Based on http://www.thingiverse.com/thing:234751 I have added a mounting point for a FRC Standard Rotary Encoder. This is a bracket to hold the Igus JFI-1012-08 Flange Bushing for a 5/8 shaft. These are a standard part of the FIRST Kit of Parts. Inventor file is also provided. http://www.igus.com/iPro/iPro_02_0017_0000_USen.htm?ArtNr=JFI-1011-08&c=US&l=en
