Just showing off a shift knob I made with a 3D printer. Has a carbon fiber ring on it for the carbon fiber fanatics.

 

 

Cool

 

Looks great man! Do you have anymore pics of it? I would like to know how much this weighs and your impressions of it as a shift knob. I know that I would be biased on a review if I made it myself ;-)

 

Here is a picture of a similar white one I made. It is just about as heavy as a stock shift knob because it has a large piece of brass in the center that is tapped to receive the shifter threads.

The good stuff about it:

1 - The 3D printed parts have a little bit of a texture so it is easy to grip.

2 - It does not get hot like the stock shifter.

3 - You can get material for 3D printing in many colors so you can match your car or print whatever color you want

4 - You can make whatever size or shape you want with or without the carbon fiber ring. Or the ring could be 3D printed any color or texture instead of being carbon fiber.

5 - Fun to make and fun to drive using something you made yourself.

The bad:

1 - Not sure how it will hold up over time exposed to the sun or really high temperatures (not sure how hot a track car gets).

2 - If you didn't make a brass center it would be pretty light.

 

If you print it in ABS it will hold up to the heat better. Plus, if you want to get it buttery smooth just wipe the ABS down with some acetone.

I usually print the helicoil thread tap directly on the part, then install a helicoil to match the car. You can also buy some brass heat set inserts and just melt them in with a soldering iron.

Anyways, looks good!
