Five unusual 3D printed gears

The most complicated and strange printed gear systems.

All of these gear systems really work, which can be tricky with 3D printing. I don’t think any of these have a practical use, but they are just cool. They would make great gifts or desk toys.

Above: Mobius gear by Aaron Hoover. It looks impossible, but it does work. The trick is that the center gear belt is made from a flexible material.

There are four more unusual gears after the jump!

    These are wonderful! Could you please post brief youtube videos or .gif files of how they look when someone turns them?

    I would love to, but these were all made by different people so I don’t have access to them. Sorry.
