Who else remembers Spirograph? When making elaborate spiral doodles, did you ever wish for a much, much bigger version? [Fortress Fine Woodworks] had that thought, and “slapped a router onto it” to create a gorgeous walnut table. This printed sanding block was a nice touch. The video covers not only 3D printing the giant Spirograph, […]
Spirographs can make some pretty groovy designs on paper, but what if you want to take it a step further? [Uri Tuchman] has used the pantograph on his milling machine to duplicate the effect in harder materials. [Tuchman] starts with a quick proof-of-concept using an actual plastic Spirograph toy to make sure it isn’t a […]
Stepper motors are great for projects that require accurate control of motion. 3D printers, CNC machines and plotters are often built using these useful devices. [InventorArtist] built a stepper-based cycloid drawing machine, and made use of a nifty little hack along the way. The machine uses a rotating turntable to spin a piece of drawing […]
