Plastic powdering machine (prototype)

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
