I have a Macross Frontier machine sitting in a Keith frame.
The problem I noting now is that lost balls falling from the rear of the machine for the most part do fall into the lower tray and roll forward... however I am getting quite a few that seem to hit the shelf and get stuck..
This then leads me to clearing the shelf when I am done of all the "lost" lost balls.

I am looking for ideas on a simple little shoot that I can have the balls go just past the lower shelf and into the collection tray.

Any ideas?
