On a knex ball machine how do you make a big tray for your balls to fall in from all directions?

I don't know how to make something like a track that can be connected to all ball tracks. I've seen a few on youtube but I still don't have a good picture. Oh and I know it's not a funnel.

You could try using Suronome's white floor:

Usually used at the bottom of a ball machine to catch the balls to return to the lift, but would technically work anywhere.
keep looking and pausing thats what i do
