Vial-Holder for BGA-balls (Dont fall out)

This is a secure holder for those BGA-Sets one can buy on Aliexpress (https://www.aliexpress.com/item/10-Bottles-Lot-PMTC-Leaded-BGA-Solder-Balls-0-25-0-3-0-4-0-45/32714733946.html).
The vials fit nicely and dont fall out, even if inverted. They are held in place by printed Claw-springs.
