This is an ice pack holder for your freezer. It is designed to separate the "slim" lunch box ice packs so that more surface area is exposed to air and you can freeze them faster than if they were all in a big stack. Each "spot" is 17mm wide with a 3mm thick separator. Some of the icepacks will lean and touch a bit, but you should see an improvement in freezing performance. If you are careful to stack them all in the same orientation, they should be able to stay fully separate.

I have included a full 8 pack version, an 8 pack version with base slots to reduce material use (and add more surface area for air to make contact?), and a 4 pack version with the cutouts.

Designed specifically for these: https://www.amazon.com/gp/product/B003FO2B5U/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

I have to freeze 8 packs at a time for a homebrewing setup, so I designed this thing. It seems to help.
