This allows you to attach a pen to your ender 3 S1 extruder. This enables you to let the printer write or even "draw" on a piece of paper. I have included my Cura Material and Printer profiles to enable you to draw easily.

I made this object to use the screws already on the Ender 3 S1 extruder head, so no additional screws needed to attach to printer. In order to secure the pen into the holder, I made a whole for an M4 screw to act as a grub screw.

2 Models are included here, one being more complacent and allowing the attachment to flex more and another being more rigid.
