A large piece of my ice bin broke off, right under the auger. It is a
17 year old Whirlpool with ice maker. I think a large chunk of ice
got stuck in the auger and was pushed down to break out the hole.

I have previously repaired it with duct tape. That works for a few
weeks. Anyone know of a better way, maybe some sort of glue? I could
replace the bin for the low low price of $53.

You need to identify the plastic to see what possible glues to use.
If room, you could consider adding reinforcement like a piece of glass
fabric.
