SunTour Mountech Guide Pulley

This is for those who want to replace the guide pulley on their SunTour Mountech or similar Tech-cage-equipped derailleur. I'm not sure this will work since it needs tight tolerances, but at least it's digitized now. I made this using a working guide pulley, keeping all the dimensions as accurate as possible. Since FDM printers are sloppy, extra clearance might be needed on the inner surface. The STEP file is included to easily make this change.

Update: I printed this and tested it out. It fits a little snug, and I think it's because of the seam on the inner face of the pulley. I think with some use, that seam will wear smooth and it'll spin a lot better. Tolerance can also be added to account for this of course.
