Part size: think about the same total volume of foam that an iPhone or an Android phone have. The size envelope is like two stacked pack of cigarrettes (obviously there are holes for the electronics and for the phones to be stuck in). I don't know the number of units or of variations yet. Once I have a working prototype and software my plan is to start a project in my local Kickstarter-alike which would tell me how many to make and, just as importantly, for how many different models of phones. Oh, and right now I am building the prototype the old way, with sheets of the material, x-acto and glue. CAD/CAM software and milled prototypes won't come into play until I have something that works. Then I will start trying to price the production. Right now I was just taking advantage of your offer to share your experience. Thanks again.
