Inspired by the Model from Rydis tools, I remodeled the insert so that the face sits more flush/planer to the surface of the dash. I also increased the depth of the bolt hole so that a cap screw will fit flush with the ball. Three ball sizes are available in the current print profile a 25mm (typical RAM), 16.9mm and a 16mm.

Additional Hardware:

25mm ball -

1, M5 X 60 Cap Screw

1, M5 Nut

16.9-16mm ball -

1, M5 X 45 Cap Screw

1, M5 Nut
