Filiastruder Hopper upgrade

So I made a new version of the hopper funnel. I didn't like how it fitted to the hopper and how thin the whole structure was. This version has thicker walls to match the strength of the hopper. It also has a recess and lip to hold the hopper firmly and give you a solid glue surface. I also curved the inside and top edge to keep the pellets flowing downward with gravity. You can print it with no support structure and remove the one I put in when your done. All of the external measurements are still the same.
