Suburban Tuning Knob

I designed this knob to replace the tuning knob (right knob) in the stock stereo of my 2012 suburban. 3 pieces in total - 1. outer ring, 2. button, 3. plunger. Assemble by sandwiching the outer ring using the button and the plunger as shown in the image.

Printing:
On my Ender3 Pro it looked best to print the button on its side instead of vertically. The doming on the top of the button is pretty subtle. Printing vertically makes concentric steps that look weird.

Print the plunger standing up so the bottom surface is perfectly flat.
