1/4 Inch Circulation Bearing
Description
This is my best bearing to date. This 1/4 inch bearing has 4 channels that the maker fills with BBs. PVCing the cap on takes a few seconds, and you now have a bearing that only takes steel shot or BBs and plastic.
Lets create more parts on our own! Forget store-bought linear bearings!

Fill with BBs or steel shot, PVC the cap in place and Voila!
I know its a big file, but I have stopped using Sketchup and am now able to create more complex designs.

I repaired it with netfabb, and printed couple of layers.
I think I should rescale it about 1.3-1.35 berofe trying to get 6mm BB's in it :-P
This is made for .175 caliber / steel or copper bbs.
Yeah, always clean any 3d model, otherwise you get a train wreck.
