DIY Custom Shift Knob

[zgastin]

I have been working a bit on designing a shift knob. Typical ricer cars that take an M10 thread on knob have it easy, we have it Audi, so a little more design is required than gluing an M10 nut into your favorite dildo and threading it on. Since we have that clamp-on boot and knob combo, I am going to make a simple threaded adapter with set screws to lock it onto the shifter shaft. The boot slides over this and then the knob threads onto the adapter. Simple, right? Exactly. I still need to cut off the one-time-use clamp to free the current knob and then finalize measurements. I should be able to scrounge up some aluminum stock somewhere on campus and then start making some chips. If this is something people are interested in, follow along and I would be happy to share prints and/or make more for people if it works/there is interest.
Design Requirements:
Use stock boot/surround
Returnable to stock (My car is on it's way out and I want to take this with me)
Easy to install

I don't know why I haven't thought of this. Good luck! Interested to see your progress

Just bought a GTI so this might not happen... Let me know if you want to collaborate on this though. I will be putting my a4 up for sale in a few days so I won't be pulling it apart anymore but would still be open to trying to make one.

Lol, how things change. Do you have any solidworks sketches, if not I'll make my own. I'll keep you updated with my progress
