Need New Battery Contact!

My battery contact had a little accident and no longer works. I measured the battery contact to be 19.50 mm in diameter. The battery I use is 2 18650. The host is Cree c8. So where do I find a battery contact this size?

Not 100% sure but I think these are what you need:
Z-Blanks 20mm Diameter - $3.00 : Zero Lasers
I am not sure who else sells them in that size.

Thanks so much
