When the sample pieces arrived, I realized that I would have to learn how to use our calipers to measure the various dimensions.
It's important to remember that consumer 3-D printers are really about prototyping or one-off pieces.
Only I saw the imperfections in the final pieces. Teacher Clare pronounced them "perfect." I learned a lot, not only about the mechanics of reproducing something in 3-D, but also about the mental approach to design. More about that in my follow-up to the rice funnel fight to the death.
