3D printer Dual Pellet Extruder

Here is the dual pellet extruder that I design and developed for my 3D Printer. It's pretty big since it needs to extrude a lot of material.
The stainless steel pipe is 10 cm long and 12.5 mm in diameter, the drill bit is 12 mm. Nozzle is 1.2 mm and is stainless steel. It's made to extrude carbon fiber and HIPS for support material.
