This is a derivative of http://www.thingiverse.com/thing:25490 here is where you can get the Bearinghttp://www.drillspot.com/products/462029/Dynaroll_SMR128ZZ_A5_Miniature_Ball_Bearing http://www.bearingboys.co.uk/MF128-ZZ_Flanged_Shielded_Miniature_Ball_Bearing-62818-p (hopefully I found the right one at Bearing Boys if not please inform me and Ill fix the link.. Everything is the same except the manufacture and the first 3-2 letters. From SMR to MF ) I seen this design printed it out (modified the Spot where the bearing went cause this was the smallest I could find) and it snapped while cleaning it. No offense I loved the design.. So I modified it heavily and added a little more support. This is version 3 if you notice from the pics you have a LARGE amount of movement with the bearing The walls were thickened and it uses all the same hardware from the original one. So all you need is the Bearing. Hope it works as good for you as it does for me. Instructions once printed take your old feeder apart and use a standard nut (not one with a lock thread) plop the bearing on and away you should go. ITs a little tight getting it in there but it works nice. BTW make sure you print it with 100% fill.. anything less will crumble under the pressure that is needed to push the bearing against the filament. One note I added little black dots to the out side of the bearing with a sharpie about 15-20 of them . Reason is so through the gap I could look in and check to see if the bearing was moving. (flash light needed for this) Great way to see if your actually getting movement on the print or not.
