The idea is to create a non-helical thread (which is just a revolution of a sawtooth profile, or a stack of disks with tapered edges). Such a fake thread is hard to tell apart from the real helical one by just looking at it. This may work for FEM, too. However, if you want to 3d-print it, this isn't going to work.
