Ender 3 Modular Plotter Attachment (Bullseye)
thingiverse
Made to work with the Bullseye mount on my Ender 3. It uses an M3x10 button head screw to mount it to the carriage and then an M3x12 and M3 nut to hold the pens in place. I use Inkscape to generate Code for the actual plotting - https://inkscape.org Teaching Tech has a decent tutorial on how to use Inkscape here: https://www.youtube.com/watch?v=CuWZWAfBsm8 And Plotterfun is an excellent place to generate .svgs - https://mitxela.com/plotterfun/ The Bracket .stl provided works for a fine point sharpie and I also have the fusion 360 file available so that you can change the size and shape of the hole to fit whatever pen you have.
