Corrado shift knob

This went through a few renditions. Originally I printed threads into the center and it was one piece but when the shifter gets hot it starts to get loose which annoyed me. So I decided to make the shifter two pieces with a hex nut spot to make for a tight fit that does not loosen.

Hex nut needed for a Corrado shifter is M12x1.5. The bottom of the shifter has a little lip for the g60 style leather boot to slip over. The Vr6 boot will not work with it but the knob will still fit.
