Prusa i3 Bearing Holder Modification

This file was modified from the parts used by the Folger Technologies Prusa i3. A few people have had issues with the original part not holding the bearing tight enough leading to slippage. The part was modified so that zip ties could be added to help hold keep everything tight. I was told that the original files I modified were from the original open source Prusa i3 design that should be available on Thingiverse. I could not figure out which Thingiverse item it was so if anyone knows it please
