EDIT – Yes, it’s a bushing. No, I’m not worried about lubrication or friction. Have a look at the pinned comment.
The question I’ve been asked the most is what am I going to use for bearings in the 4x scale OpenRC F1 project. Finding the proper sized bearings was going to take more time and effort than I had. I needed to use 3d printing to solve this problem, and the solution works INCREDIBLY well.
