The file 'Bearing Holder For 15mm OD 8mm ID 5mm Wide Bearing To Improve A Harbor Freight Rock Tumbler 3D Printer Model' is (STL) file type, size is 27.8KB.
A simple bearing holder for a 15mmxODx8mm IDx5mm thick bearing I whipped up to modify a Harbor Freight rock tumbler. It is to replace the tiny plastic guide that contacts the barrel to keep it from rubbing on the frame that is wearing down really fast after only a week. The holder should mount to the frame with 3mm bolts after holes are drilled. There is an inner bushing that goes into the center of the bearing that should assemble with a 3mm x 15mm nut and bolt. The mounting slots are also for 3mm bolts.
