Rubbermaid 2 Cup Holder

thingiverse

I don't know why all tupperware like this doesn't come with the tops stackable on themselves. Who stores these empty and fully assembled? I decided to fix this with a holder to keep all the tops stacked up. This is good for 8 of the small 2-cup / 473ml units. I find these are about the right size for storing leftovers in individual portions.
