This project was inspired by a commercial product called AxiDraw
It was a combination of reasons that made me consider to do it myself, cost, availability and customs playing a role in the equation that, and having a 3D printer at home
This is just a drawing machine quite similar a to a pen plotter but that can adapt to any size of document and any type of paper.
It can use regular felt-tip pens, ball pens or fountain pens as pen orientation is variable. It is a new version of an XY plotter using a single belt and two stepper motors in a configuration called h-bot.

AxiDraw

The AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with your favorite fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself.
You can Do it by hand with free stl file and print it
