Polargraph Plotter

A Polargraph plotter is a type of drawing machine that uses two stepper motors to control a pen suspended by strings. The pen is moved by adjusting the lengths of the strings via the motors. However, you have seen many types of Polargraph or vertical wall plotter but this one is different. I have designed this plotter using cheap parts and 3d printed parts. This plotter is very compact, easy to assemble, low making cost as it uses only 3d printed parts, old selfie sticks, an Arduino Nano, two 28BYJ-48 stepper motors, and a servo motor. The Width of this Polargraph machine varies from 375mm to 690mm. So you can plot different size of designs on a very small to very large space.
