![]() When 3D printing is not needed, a simulated thread is often sufficient for visualization. Right: simple bolt with a real helical thread. Left: simple bolt with a fake, non-helical thread. This method is good for visualizing a thread-like object, but it is not useful if we need to 3D-print an actual thread. This fake thread is hard to tell apart from the real helical one by simple inspection. We can create a fake thread by using a non-helical path, for example by revolving a sawtooth profile, or by stacking discs with tapered edges. In many cases we don't need real threads, we just need a visual indication that the threads will be there.
