For a while now we’ve been tinkering around with the idea of a pen attachment for the printers. The idea is that it could give users a lot more choices of ink and paper for good old 2D printing, including any available pens/pencils/markers or even etch-resist pens for prototyping circuit boards.
After seeing Wolf Robotic’s awesome scara arm 2D marker printer at the mini maker fair this weekend, I made up this primitave pen mount that should fit any TAZ printer and any of the soon to be released mini printers. I’ve attached the stl and source files of the pen mount, you ought to be able to clamp it under the printhead using the m4 screw under the left side of the printhead, or use the freecad file to adapt it to whatever printer you like. The attached Cura configuration will let you print a 10 layer pen print, just load a high contrast jpeg into cura and set the total print height to 0.05mm, the 1st layer to 0.01 and the size to something that fits your printer. The mount is designed to hold a bic ballpoint pen, but should hold most other pens. It’s pretty great to watch

I’ll test the mount on a TAZ tomorrow to make sure it works. As always, the design is Creative Commons - Share Alike.
