20mm Aluminum Extrusion Recirculating Bearing Carriage

Based on the original design located at https://github.com/jcrocholl/recirculating

and

This is for 20mm Extrusion and uses 21 5/16" acetal balls/spheres. The original design is for 15mm extrusion and uses a different profile for the ball track. Right now I am only uploading the 20mm version, but I have the same profile for 15mm. The track on this bearing prints easier and in my opinion has considerable smoother action. This is a work in progress and has not been fully tested. I am still playing around with different carriage plates and will add those when I have something that works well with this bearing.

Should work with M6 hardware.
