*Update 2020-11-16: Created a better system for locking the arm clamps in place. I also added a wheel that would be considered a crappy blower fan. It has a lower profile and allows you to use an air compressor or canned air to spin the wheel. If you are upgrading an earlier version, **DO NOT** attempt to use the blower wheel without the newer clamps and base.*

I was looking through 507 mechanical movements when I saw this rather weird looking mechanism. So I decided I needed to have my own and drew one up in OnShape. I really like the way this model moves it really is interesting.

You need to print one of everything except for the arm clamps which you need two of.

Everything just snaps together as shown in the video.

You should be able to print this on any printer as all of the tolerances are 0.5mm
