Fully 3D Printed Gear Knob (50mm Ball, M12x1.25)
thingiverse
A Gear knob for cars, threaded M12x1.25. Can be centred with a small lock nut. Next revision will have space for an M2 grub screw for precise positioning, maybe an integral locking nut. We'll see. NOTE - Please be aware that some jurisdictions require a visible H-Pattern located either on or near the gear shifter. Please make sure this is legal for you and abide by all relevant local laws and regulations before putting it on a street car. Personally, I would require a sticker/decal of the gear pattern within 10cm of the stick.
