This is an eight part spinning mechanism which is apparently called a Trammel (i don't know if it actually is called that). This device is meant to draw ovals, but it is also just a lot of fun to play with. Unlike other designs, this used three sliders instead of two. It has a very smooth feel when spinning and is easy to print (takes 2 hours on 50% scale, 200 micron layers). Designed by me in Cubify Design, with the inspiration from a gif a friend showed me. Feel free to comment any improvements to be added.
