Chompy, The Filament Shark

Chompy, The Filament Shark cuts the ends of your filament leaving a nice 40º shark bite across the end of the filament. Chompy doesn't leave filament ends everywhere, and has a big stomach for holding many filament ends.

When Chompy is full, just lift the (magnetically latched) fin to let it poop all the waste filament into the bin.

This is a relatively simple print. No support required.
