Cadbury Egg Cup (Q42711)

After building a Thing-o-Matic I had to create something from scratch. I was inspired by a nearby Cadbury Creme Egg and made this small egg cup. I was designing it with CSG in my head with the idea of using OpenSCAD (cylinder minus torus minus sphere, basically) when I noticed the Alibre icon and decided to see if "revolve boss" would get the job done quicker. In some sense the design is parametric, since you could load the AD_PRT file and modify the dimensions in the sketch (or even drag the shapes around within the constraints I set, like the 3mm top lip). Update: Perhaps it inspired this real egg cup? http://www.thingiverse.com/thing:6620
