Ghostbusters Ghost Trap Knob GB1 1984 Heathkit

This is a model of the Heathkit Radio knob used on the Ghost Trap in the 1984 film, Ghostbusters. I made the mounting post compatible with countspatula's trap kit. While this is not a perfect model, it is based on the dimensions of the real knob. I am still learning to model in 3D, so some of the spacing between the ribs is not precise. If anyone wants to make a more accurate version I would be happy to collaborate with you and provide you with any measurements of the real knob that you need.

Update 2/20/2020: The opening in the knob was too small for the post. I have corrected it, but it is a tight fit. I would recommend sanding down the post slightly.
