4th Gen Camaro / Firebird Shifter Ball

thingiverse

I designed this because I didn't find any PLAIN shifter knobs, so you can leave plain or add your own design. I printed mine with infill almost maxed at 80%. This will help the Knob threads to be as strong as possible and it gives it a nice weight. This print will take a while and of course with infill higher will take more filament. I added a Test Nut, make sure the thread on the Shifter will work for you. Print the Test Nut with lower infill, this is just to check the threads.
