Thought I would mention this because well, it is just really cool. I found this company that can take almost anything as long as it is dry and under 2" long and mold it inside a shifter knob. I sent him a Donald Duck pin and it came out awsome! He even gives you a nice little sleeve to cover the exposed threads. The company is called "kool knobs", you can find it online. Not trying to advertise for him, just figured it was something that a lot of people on here might enjoy having in their cars.
