I finally got a moment to set up the camera and the 3-D printed mugs. As promised, here's some photos.
I tried drinking out of one--or rather, pouring into one--and it's easy to splash things all over. They hold a tablespoon of liquid.
Talking with E. S., and she added absinth to the list of things one could drink out of these.
I'm pleased with the way that they turned out; the end product is very close to what I designed, so much so that I can see that I could have easily added more faces and vertexes to the design and the print would have come out more like a cylinder and less prism-like.
