I decided I needed a new shift knob, here it is. I printed it at high infill. It's ended up being way to big. I went to resize it, but the pips used the edges for reference and they moved all over the place. I decided to enlarge the mounting hole and then reduced the size in print. It worked out well I think. I was worried about it holding up to the heat in the summer in SoCal. But so far, no problems.12/24/2016 Update: 2 1/2 years later and still no problems. It's discolored a bit and the acetone vapor smoothing shell has crazed as seen in the lastest picture, it actually looks antiqued now which fits well in my '61 pickup truck.Print at 50% infill or higher for strength and print at 75% of the original size and it should all be good. I used a drop of black nail polish in each indentation to accent the pips as well.
