I took the profile from the feet that UEPONYA made and used that to create these feet. They fit a standard racquetball which I got off of Amazon. These feet eliminate almost all the noise from the printer which is crazy loud since it doesn't come with any feet to begin with. Fans are now the loudest part on the printer.
I added the .f3d file if you want to remix it.
