Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5367667.

Just an attachment to turn a Davinci Pro printer into a pen plotter.

NOTE: This requires bdwalker1's E3D mount and the listed fasteners available here: https://www.thingiverse.com/thing:1328848/files

Additionally, this requires 2 M3 nuts and 2 M3x10mm machine screws to attach the modular holder for the pen(s)

NOTE: I just have modular pen holders of different diameters until I settle on how I want to add a spring to ensure pen pressure
