Here are two shift knob designs with most common thread pitches to choose from:

M12 x 1,25

M12 x 1,5

M10 x 1,25

M10 x 1,5

Knob sizes:

Knob1: lenght 80mm, diameter 40mm, thread depth 40mm

Knob2: lenght 90mm, diameter 40mm, thread depth 30mm(starting from 40mm inside the knob)

The knob1 has thread starting from bottom so it might stick out depending on the original design and the knob2 has the thread starting from 40mm inside the knob to hide the lever.

The example car in pictures is Corolla E12. The knob has been in use for over 2 years now or approximately 25000km and the knob(knob2) does not show any wear or loosening(printed with PETG). I would advice to stress test the knob first before driving the car and adjust the print settings if the knob feels loose or gives any signs of breaking before use.

DISCLAIMER:

These knobs are not necessary street legal and I assume no liability for any damage, injury or misfortune as a result by them.

The car in question has passed the yearly inspection with this knob but the regulations may vary depending on the country, so make sure to follow the required regulations.

Use these knobs at your own responsibility!
