8/26/2015 – Added link to third-party update to design

As I am currently in possession of an Ultimaker 2 from the AMP Lab to create prototypes for yet another project, I’ve had the chance to thoroughly explore amature 3D printing and some of the software associated with modern sub-$3k 3D printers. I’ll leave the software issues for another day, but here I’ll detail a custom extruder design that addresses some major problems with the existing extruder implementations.
