This is a customizable knob for rotary encoders. The original model from llegoff had a small indicator mark on the top. I have switched that out for a round finger detent. I have also added some additional customizations that you might want to do.

You can customize:

• Basic
  • Knob diameter
  • Knob height
  • Shaft length
• Advanced
  • Roundover size
  • Finger indentation size
  • Number and size of detents around outside
