Stackable Container / Pill Box

I regularly go on multiple day trips and I needed something to carry my daily dose of vitamin pills with me. Because the trip length varies every time (usually between 1 and 7 days), I wanted something flexible. I also needed something large enough, because I take quite a few vitamins. So this is what I came up with! I'm new to designing and this is only my second design ever, so I learned a lot along the way.

These little containers also double as a lid for another container, so you only need one real lid for the top container. They have a diameter of 5 cm (1.97") and are just a little over 3 cm (1.22") tall.

They can be printed without supports, although a brim is probably recommended. The walls have been designed to be 1.2 mm thick, so it plays well with all common nozzle sizes.

If you fill a container to the brim, you will need an actual lid to close it. If you would use another container instead, you would smash the contents due to the way they are designed.
