This is a set of printed parts to make an Idler from a 608 bearing. The top and bottom caps snap onto the 608 bearing, and 2 bushings provide a 5M hole in the center.
04/29/2017 Added idler608_01B that is the same as the original except the height or the 2 bearing clips (2 larger parts) has been stretched by 0.25mm for better (depending on the filament used) clip holding.
NOTE: A touch glue may be needed to keep it all together, I'm not sure. I didn't use glue...yet and seems to be holding up, but the Z axis is not a high speed axis.
I used Filament Innovations Carbon Fiber X
