Tesla Shift Knob with Adapters

Couldn't find a shift knob I liked to replace a broken one on an electric MJ-1E at work so I made this Tesla branded one in Tinkercad. I wasn't sure what thread size/pitch I needed so I made it with a hexagonal insert so you can quickly try out different threads and then when you find the right one just superglue the insert onto the main knob. Also helps with easier alignment since you can thread on the insert first then push the main knob on lined up correctly.

I've included the 3 most common thread sizes:

M10-1.25
M10-1.5
M12-1.25
