This pen plotter allows you to turn your Ender 3 S1 into a 2D printer so you can draw pictures by attaching a pen to the print head!

I couldn't find any pen mount to my Ender 3 S1 printer that I liked, so I made this simple one for myself. I like it because:

1) You can leave it permanently attached to the print head. It's simple and low profile.
2) It's quick and easy to attach the writing device. Just grab two rubber bands and secure the pen.
3) You can use almost any kind of writing device (pen, pencil, marker).
4) The rubber bands allow the pen to flex a little when it touches the paper, compensating for slight changes in bed height and avoiding damage to the pen, paper, or bed. I've found that other models that use springs don't have enough flex.

It attaches to the side of the print head using the two screws (which are already there, no need to get other screws). No supports needed.
