My VW was missing on of the knobs to tune the radio, so i printed one. It fits a little loose (if you dont have the little metal clip), but after i put a few layers of paint on it, it fits nice and snug. These knobs should fit all MK4 radio's (all VW vehicles from 1998.5-2003)..1mm layer height 2 shells After the print i painted mine so i could get the little white line, and to make it fit more snug.
