I've been interested in designing a few items in ceramic. In an effort of learning about the material and generating ideas, I created a Vented Coffee Cup series that doesn't have a handle. Ambient air should keep the outside of the cup cooler and easier to hold.
Once I get the price and design to meet in that sweet spot, I plan to produce one or two of these coffee mugs. At least that way, I know that they will not fail any manual checks during the production phase at Shapeways.
