Eder 3 Draw-Bot Mount+Cura Profile

thingiverse

A simple attachment designed specifically for pen plotting on a standard Ender 3 head. The mount is tailored to accommodate Stabilo pens, making it versatile enough to work with low-profile pens/pencils featuring hexagonal profiles. The pen holder, extruder mounting bracket, and optional attachment all interlock via friction fit and can be reinforced as needed. A threaded hole within the pen holder accommodates an M4 screw/bolt, 12mm in length, though a 10mm may also suffice. Printing works effectively with just one pen mount; however, I've included an additional optional one to enhance stability and maintain the pen's upright position. The interior of the pen holder features a tapered design for easier insertion, be certain to identify the thinner side and orient it downwards on the mounting bracket. The angled arms of the extruder mounting bracket should provide sufficient hold but can benefit from a small strip of tape (especially useful during high-speed printing).
