Turny Handle Thing (Trammel of Archimedes)

thingiverse

I'm still figuring out what to call this thing. It's not an original concept by any means, but I wanted to finally create one for myself. There's something really satisfying about assembling all the pieces and getting that cool ellipse to work. PETG or flexible filaments are perfect for this project because they snap into place easily. Don't forget to print two sliders - you'll need them to attach the handle correctly. Make sure those sliders fit snugly in their tracks before attaching the handle, or you'll struggle to put it together. It's not a masterpiece, but I'm really happy with how it turned out. If you like it, feel free to give it a try yourself and see what you think.
