Let’s see what you guys think this is for.
Let me take a guess. 1251 has been teasing us with that pink thing 2 years in a row now. That is going to be the roller which will be used to collect balls. 
Oh no! We’re using the same tread on a roller, however ours are much wider. I’m going to go ahead and guess this is one of many small rollers for power feeding.
Its obviously how those people in Florida make hotdogs. :-p
Its either the ball harvestor conveyorbelt, or a really bad waffle maker.
Either a roller pushing the balls into the shooter, or it’s a hip cool rad bumper.
im going to take a wild guess on this one- a ball shooter? It looks similar to something we prototyped…
our shooter rollers are almost identical to yours! but you have the advantage of pink PVC pipe…
maybe its just the photo but it doesnt look like pvc…
Your right it isnt pink pvc it is UHMW (ultra high molecular weight polyurethane).
