RepRap Pen Holder (Plotter Extruder)

thingiverse

This pen holder is designed to be attached to one of the spare extruder mounts on a RepRapPro Mendel, making it perfect for holding a pen during general purpose plotting or, as in my case, PCB plotting. To use it, you will need 4x M3 20mm machine screws, 4x M3 hex nuts, and 6x M3 flat washers. Load the design into OpenSCAD, customize the pen_dia variable for your pen's diameter, print the holder, mount it on your printer, and start enjoying your pen-assisted plotting projects! If you're using a 9.5mm diameter pen like the Staedtler Lumocolor 318-9, simply print the STL file without any further customization.
