Idler Pulley Conversion - 525 ZZ Bearing Cobblebot

I had some bearings leftover from my Cobblebot build and other spare parts. I needed a few Idler pullies for a belt system I was working on so I designed this conversion kit.

The 2 outer pieces press fit onto the outside of the bearings and each other to create flanges for a GT2 Timing belt to rest in. I created these because some people felt the larger pulleys created too large of a track for the belt. In some situations this is probably true so this may work better for some people.
