Ice tray holder

I have some silicone ice trays that I used to pile up with aluminum sheets in-between.

I printed these to separate things so that 1) it doesn't freeze together into one big lump, and 2) it doesn't wobble and fall over when I'm trying to put it in the freezer. It fits in my freezer with about an inch clearance above it.

All 3 pieces take about an hour to print together on my Prusa MK3.

The aluminum sheets are K&S Engineering #3071 6061-T6 Aluminum Sheet, 6" x 12" x .090 hobby items from Amazon.

I also included the FreeCAD files I used to design it.
