Ok, I bought the app and after playing around with it a bit more and Tinkercad, I have to say it has some nice features. Being able to subtract any shape from any other is great. As a test I wanted to build a small round bottle similar to what one would see holding a potion in a game. This involves subtracting one sphere from another, a hollow cylinder and a little donut for the lip on the bottle. Once I get it done I'll try to post it somewhere. With a quick search I did find this one (http://www.thingiverse.com/thing:208592) that is almost completely doable in Morphi, the only hard part would be the dent in the bottom.
