Gears are a piece of machinery that are used in nearly every transmission and mechanical machinery. These small pieces of machinery can accomplish a lot of goals depending on the context and its particular design. This also means that you can sometimes deviate from the traditional circular format and bring some variation. Some of these are done with practical applications and other without any purpose or application. The series of tetrahedral rectangular gears mentioned here are some of the most ridiculous and impressive gears we have seen so far.
These tetrahedral gears are designed by Henry Segerman. These gears are not designed for what they can do but what they can demonstrate. These are really impressive illustrations of how far the 3D printing technology has gone. Once printed, they become one of the most impressive desk toys.
