I don't really see how it plays on Eve strength.
Like poster before me said, there's lot of competition, the market is extremely niche, there are already some pretty great examples of how to do it well - what Eve could offer here?
They don't have the biggest budget, supply nor design arm. They do have the Community, but I don't really see 1) that many people here are that into 3D printing and would play to spend the money to bring Eve's 3D printer to life 2) how Community itself could help with designing one.
Obviously, it is an idea, and interesting one at that - I just doubt it's the right idea for the right time and place.
