Logitech Gear Shifter Knob + Adapter *SIM RACING*

For the shifter, I used ABS material. After printing, I sanded it with 180/320/500/800 grit papers and polished it for a better finish.

If you use 100% infill, the knob will feel more solid and, in my opinion, it will be better to use.

I used PLA to print the adapter and used the factory screw.
