Fish Food Funnel

Our automated fish food feeder tended to spill the food outside the tank because it's a cheap 10 gallon tank and the feeding hole in the lid is relatively small and/or not designed for the feeder we're using.

For a while we had a piece of plastic in there, but my wife had the idea to 3D print a funnel!

After a couple of iterations, we arrived on this design.

I printed the main part of the funnel at 100% infill, and the block that attaches to it at 10% infill to save on material.

I sliced the model in half in netfabb free to permit easier completion of the above two-part print.

Designed to fit the feeding hole of the below aquarium hood:
