This time a variant of the Archimedes' screw type module. This one can't be reversed - balls are transported forwards regardless of rotational direction.

Hey that's pretty neat! Does it need to go 'forwards' at least some of the time to feed balls in from the bottom? Or will it work if it goes 'backwards' the whole time? Either way, I'm impressed.

It can feed in either direction. When going backwards, it will drop some of the balls back into the centre. Enough balls will make it through anyway.

That is awesome. I also very much like the finished look of your module.
