Printrbot-Plotter Marker Mount

thingiverse

This mounting bracket attaches a marker to a Printrbot, creating an improvised pen plotter. Insert the marker from below and secure with an M3 screw after reaching the right depth. Mount between Extruder Mount and Extruder (on some printers). The provided STL has been cleaned up in NetFabb; it's a derivative of pb-Xtruder-Mount-v2.skp by Brook Drumm. Note that you may need to file the lower lip of the hole, and adjust the distance from holes if required (version 3 files address this).
