Crank Slider Trammel - 608 / 22mm Bearing slides
Description
I spotted one of these on a show about ancient architects I figured I'd try to make one! The original trammel has two locked squares and created an elliptical shape when rotated. Figured I'd add another slider to it. When turned at speed it looks like a wankel engine! I have heaps of 608 bearings from a fidget spinner phase I went through so put them to use in this :) It's a large print so I'd recommend printing one slider and a part of the base and testing the fit of each piece. I made it with tolerances to suit my printer (0.2mm) but they might be too loose / tight for yours. YMMV. If you make one I'd love to see it!
