About this 3D model

Here is my powdering machine project. I've just made a first prototype for the machine and there's still a lot of things to do in order to make this machine better. This machine can be used to powder plastic garbage and other material into filament material needed in 3D-printers fillament makers. Drum rasp inside this machine can be found from Amazon Wolfcraft 52 x 30mm Drum Rasp with 6mm Shank http://www.amazon.co.uk/Wolfcraft-2520000-30mm-Drum-Shank/dp/B001W7JWPY First test run video on Youtube http://youtu.be/GcUE187Tlvs
