Two part knob

Updated 1/17/17:

Two new types of multi-part electronic control knob designs:
Fill holes with Fima (bake at 110 degrees in toaster oven 30 Min or use two part plastic resin)
- knob2 has a paddle insert instead of a central well.
- knob3 has holes that can be filled with paint or 2 part plastic resin.

This project demonstrates a 3D printed two part radio/electronics knob.
The top part pressure fits snugly in the base.
The top can be painted a different color or may be printed in different colors of plastic.
