Hello Logan74k,
I just registered myself here because I love your Skull Shifter Knob design.
I like to make a tin cast of this for my and a friends car. Any chance I could have the *.stl file from you? I own a 3D Priter, will print it in ABS, smooth it with acetone, then make a silicone mold from it and cast it in tin. Im not good in designing organic stuff like this knob, I only could do some qubic designs in Inventor ^^ and this is why I ask your support.
Greetings from Germany!
