YETI 12oz to 16oz Can Insulator Spacer

This spacer lets you use a 12oz can in a 16oz YETI Colster Can Insulator, as well as other can insulators, as it just takes up the difference in height between two different can sizes. But is has an additional feature, which is to hold a Rabbit Jumbo Chilling Stone. The stone friction fits in the opening and helps keep the beverage and insulator extra cold.

The stones aren't exactly square, so one orientation seems to fit a little more snugly than the others. But it can stay with the spacer and go right in the freezer when done, so it is always ready for use.

Of course, you don't have to use the chilling stone, and it will still work as advertised. :)

I printed it in PETG, which seems to be my material of choice for holding up to the outdoors and being possibly left out in the sun on a hot day. But no support material is required, and I even skipped a brim altogether due to the round shape (no stress risers) and good 1st-layer contact area.

Enjoy!
