Bolt from "Iron Giant"

thingiverse

My son is absolutely fascinated by the movie, and I thought it would be fantastic to recreate the iconic bolt from the Iron Giant's ear for him. However, I did take a slight creative liberty with how the thread terminates, as it appears to transform into a ring of the same diameter as the major diameter instead of coming to a chamfer or spiraling inward like it would in real life. Although I managed to overlook the cone-shaped tip being ridiculously oversized and making the thread utterly useless, unless the Iron Giant's ear has an appropriately sized split nut that engages at some depth, which somehow renders the weird thread termination issue irrelevant.
