Curt 51170 Brake Controller knob for reference

I quickly modeled the Curt 51170 Spectrum Brake Controller knob so I could double-sided tape it to my dashboard to see where it won't interfere with my knees before purchasing it. I used Curt's reference drawing. It looks like it fits in a mount so it will stick out a little further in real life, but it's close enough to help visualize.
