Step 1: Tools and Materials.
> A binder/ file folder... it needs to be material that snaps back to its original form after bending it
> A piece of paper and pencil (for the template)
> Scissors or heavy duty snips of some sort to cut the plastic
> Your hopper of course
> some kind of measuring device to use as a reference
Step 2: Make the Template 1
Then to make it easier on you, keeping it taped down, I cut the part sticking up into thirds down to the plastic.
After that I folded the middle part down as you can see in picture 2 and made a mark about a half inch above the lip/edge. With these rough dimensions you can create your template. Mine was about 7" (long) and 4 1/4" (radius/ height)... so not quite an exact semi-circle
Step 3: Make the Template 2
Finally I experimented with some different cut-outs and found that the fewer finger like things you have going into the hopper the better, otherwise they get cramped in there and it looks like an awful smile.
Step 4: Cutting and Installation
You can then poke holes where the screws go and screw it on, put the plastic fingers under the top lip and be the quickest loader on the field!
Its very efficient, you just push your pod right into the fingers and just about all the balls go in the hopper depending on how much pressure you are getting from an opponent! The best part is they stay in the hopper extremely well!
