Springy Pen Holder for Monoprice Select Mini

# What is it? This thing lets you mount a pen, marker, or drag knife to the Monoprice Select mini to plot, draw, engrave, or cut things. It adds another level of things you can make and do to your 3D printer. # Tell me about it? I saw Arpruss's cool springy pen holder, and wanted one. I originally remixed it to add the little mounting ears for the MPSM fan holder. Unfortunately that wasn't rigid enough. The Pen flopped around horribly. I redesigned it to fit snugly around the heat sink to prevent this. With this modification the pen is very rigid in all of the non-springy directions. # How do I print it? It requires support to print, unfortunately. I printed mine on the MPSM, and have attached my .gcode file if you want to use it. It's set for a bed temperature of 60C and a filament temperature of 200 and 205. This seems to work well with the White Monoprice brand PLA. You also need two #6 self tapping screws or a similar metric screw to hold the pen in place.
