Fish Food Grinder

I have 2 guppies and we have flake food. I can't give them a whole flake, it is too big. We have to grind them in our hand. So I wanted to 3d Print a grinder to make the flakes ground up so I can make mass quantities. The file is a packed build plate. Block supports in the obvious places. Like the hopper.

UPDATE: It sucks.

I have not tested this... Yet
I will test it and remove the "Thing in progress" banner.

I will make instructions on how to assemble it when I make it. I don't know if it will work.
