High speed filament pelletizer

Hi
I would like to share with you one 'thing' that i've been working on in the last few days: an high speed filament pelletizer.
It is easy to manufacture, inexpensive and simple. It transforms 1 meter of filament back into pellets in ~2 seconds:

It works great and I think the photos and the videos are self explanatory about how to build it and use.

I'll use it to recover the filament t
