Shift Knob for Logitech G29

thingiverse

Measured to exactly fit my hand! It has a cavity inside so you can add weights to your liking, you can use fishing sinkers to do that, they work as charm. Once you are finished, just put gently the bottom, it will fit. I've used PLA850 - Sakata 3D Magic Silver. No supports needed if you put the correct placement, infill with at least 40%.
