Skull shifter knob for Golf MKIII (M12 nut for fastening)

thingiverse

EDIT: I think i did something wrong during while designing this so it doesnt fit a m12 nut straight off the printer, i had to do a bit of grinding to get it in and i wont be updating the design since this was a one off for myself. I wanted a skull shifter knob for my Golf MKIII so i modeled two parts to enclose a m12 nylock nut so it would screw tight onto the stick and a lip on the bottom of it for the shifter boot. I then combined my top bit with the skull. The top and bottom are held together with 3mm screws threaded into the plastic. As these are they will require cleaning up. The bottom is done, did some sanding to get it smooth and had to grind some material out for the screws. Printing it right now, will post pics when done.
