Eder 3 Draw-Bot Mount+Cura Profile

thingiverse

A simple mount designed to allow pen plotting for a stock Ender 3 head. Specifically designed to hold Stabilo pens, the mount should work for any low profile pen/pencil, especially ones with a hexagon profile. The pen mount, extruder mount, and optional mount all friction fit together and can be reinforced if desired. The hole in the pen mount is designed to be threaded with an M4 screw/bolt. I used one 12mm in length, but you could probably get away with a 10mm as well. I find printing works well with just the one pen mount, but I've added an optional second one for increased stability, and to keep the pen upright. The insides of the pen mount are tapered for easier insertion, make sure to find which sider is thinner and place that face down on the mount. The angled arms of the extruder mount should also provide enough hold, but a small strip of tape can reinforce it (useful for printing at high speeds) UPDATE: I've added a version 2 of the extruder mount that keeps the arms perpendicular to the main body. If you have issues with the arms snapping off, try this version instead. I definitely recommend adding a layer or two of some thin padding (I used Duct Tape) to the arms so they have more of a grip.
