The file 'DrawingBot With Improved Head And Rotate Pen (for Fountain Pen) 3D Printer Model' is (stl) file type, size is 281.9KB.
Based on DrawingBot by MakerC, with 5 new 3D/STL files that you can use to add improved slider stability for the head, including pen-tilt. You can set the rotation in 3 variations (straight / 25 degrees / 50 degrees).
In this build I've used a servo (MC-375DD), which has a slightly longer shaft section.

Parts used to build:
Arduino code: (compiled and uploaded using the Arduino IDE; make sure to update config.h in your /Arduino/libraries/grbl folder to enable CoreXY !!!)
[More info on CoreXY here: http://corexy.com/theory.html]
Grbl Arduino firmware 0.9j (with stepper support) --> Use Gcode command M03 S050 to tilt the servo to release the pen; Use Gcode command M5 to raise the pen.

Next STL upgrade to come: carrier that can rotate and lock for a fountain pen (45c angle)
