A pen plotter toolhead, compatible with Ender 3 3D printers.
The pltr (pronounced "plotter") is a 3D printable toolhead for Ender 3-style 3D printers that converts a 3D printer into a 2D pen plotter. I designed the mechanical components in SolidWorks, created a tutorial for generating .gcode with Inkscape, and released all files on Github.
The project received enough interest to launch as a limited-run DIY kit, with a total of around 50 units sold.
