Abstract
A drive shaft for coupling with a drive gear having a gear shaft extending outwardly therefrom. The gear shaft includes a twisted triangular coupling hole having defined vertices. The drive shaft includes a cylinder flange joined to one end of a drive shaft cylinder, the cylinder flange having a concentric shaft extending outwardly therefrom and a plurality of members extending longitudinally outwardly from the concentric shaft, wherein the members are adapted to fit within the twisted triangular coupling hole. The plurality of members may include parallelogram-shaped prongs. Alternatively, a rod extends outwardly from the concentric shaft. The rod has three skewed blades that extend radially outwardly therefrom. Another aspect is a material supply module including a drive shaft.
