When amount of filament is decreased in 3D printing (FFF), striped patterns and various patterns with fine holes are generated. I wrote and showed such patterns in my blog in Japanese and wrote several papers on this issue. Researchers in MIT applied such patterns, which people usually try to avoid, to clothes. I wanted to develop practical applications of such patterns, but I could not find one.

By using the helical 3D printing method, a cylinder with screws can be created by a single roll of filament. Screws are formed both on outside and inside of the cylinder. So, if forming multiple cylinders with close radiuses, they can be screwed in each other. I took some photos of such nested screws.
