This strainer sits around 1cm above the bottom of the Ikea 365+ rectangular stainless steel food container (205.803.19). I use these containers next to my pizza oven for my topppings, and use the strainer for the one with diced mozzarella. Without the strainer the pieces of mozzarella on the bottom get a bit too wet.

This strainer probably also fits in the glass container.

Update: tried the glass container and it doesn't fit. The strainer sits about halfway the container, so way too high. You could print it a bit smaller though, maybe 95%.
