About this model

My son was a fan of the movie. I thought printing the bolt from the Iron Giant's ear would be a neat experience for him. I took a little artistic liberty with how the thread terminated. It didn't sit well that the thread helix appears to turn into a ring with the same diameter as the major diameter. This is instead of terminating at a chamfer or spiraling inward as it would if it were a functional part. Although I was somehow able to ignore the cone shaped tip being such a large diameter, making the thread useless anyway. Unless the Iron Giant’s ear had an appropriately sized split nut that engaged after some depth. Well that makes the weird thread termination issue not an issue.
