Shifter Knob - Exchangeable Top Part

thingiverse

So the shift knob prints in two parts, both without supports. I'll be adding some iterations I've made with and without the shift pattern. The bottom part printed in ABS or ASA smooths out perfectly with acetone, but you have to be careful with the top part - first time numbers all just melted. It needs a few cycles of tightening and loosening until it goes on smoothly.
