I used my M2 MakerGear to print an entirely new 3D Printer. Don't Believe me? Click on a link to my build video below:

The project took about 200+ hours of printing)with PLA (25% infill). The project consumed about 3kg. Overall cost was $300. Firmware of course is Marlin on RAMPS 1.4. Let me know if you have any more questions. I accessed the viability of this printer in the video.
