This is the "Bunny Knife," inspired by the popular “Carrot Knife” in China, also known as the “Gravity Knife”. 
However, bunnies eat carrots!

For this model, you'll need a well-tuned printer. I attempted a multi-colour print, but encountered a layer shift and didn't want to wait another 17 hours. If you do a multi-colour print, please share! I would love to see the results.
