This bolt was primarily an exercise on how well (and quickly) I could design a threaded bolt in Sketchup Free (web app version) without any plugins. I've got it down to about 5 or 10 minutes. I also have a 2003 Spyder, so I made it the size of my tow bolt and added a screaming chicken logo to the bolt head. Bolt is 40mm long. You'll want to invert it in your slicing software before you slice to get the big end down.
Printing at 0.2mm is sufficient with most materials.
