Tape dispenser that really cuts

Finally, a tape dispenser that really cuts!

With only 19g of filament, you get a super functional part.

I've been experimenting for a long time, but found no good solutions.

Version 5 finally worked - the two cutting tips pierce through the plastic tape excellently.

The part was divided into the roller and the cutting tips to avoid needing supports and to get good tips.

Simply join the parts with the dovetail piece.  

And if the tips become blunt, you can simply print new ones.
