Summary
A replacement for the cheap imports with to much play or slop in the main hole. These make a press fit for either plastic drylin bushings which are very quite or you can stick with ball bearings. The 4mm x .7 tapped holes are just predrilled since I am not comfortable with threads that small in plastic. Just hand tap after making or edit the design.
