Disease Markers for Pandemic

I couldn't find a full set of disease markers that I really liked. Plus, I wanted them to at least come close to looking like the diseases pictured on Pandemic's storage "petri dishes" and nothing looked like those, to me. So as my first set of designs, I came up with these.

Most of them are approximately 10x14mm. (Black is something like 12x12.) All of them are 8mm high. At these sizes, they all fit in the petri dishes, but you do have to make sure that they're not on their sides -- which can be a bit of a pain. For reference, the original cubes are all 8x8x8mm. You can try shrinking them down, but if you do, I think you'll need a smaller nozzle size than I used (.4).

Last, some of the thinner bits look pretty fragile. I was worried about that. I'm sure you COULD crush them with your fingers, but you'd have to try pretty hard and I think it would hurt. They're a lot stronger than they look.
