no difference from the originals
The author remixed this model.
After reading others reviews, I realized the printed teeth may be a problem, I was just using my packing tape dispenser and was struck by inspiration!
Removed the plastic teeth, and added 2 holes to mount a metal blade - salvaged from a Scotch-brand disposable dispenser like this one:

I mounted the blade with 2 rando plastic screws I found on my desk (origin unknown). Should fit a M2 screw…? max depth 10mm… may need to ream out the holes with a tiny bit first.
The plastic “rivets” are easily cut (behind the blade, for less crimson-leaky band-aid requiring goodness). Once removed, the blade can be cut in half to make 2 tape dispensers. DO NOT USE your nice flush-cutters to do this! A Dremel, or linesman's pliers works well.
