Export a mesh
Hi, I'm a 3D artist and would also love to try out the export mesh function. I guess the .obj extension would work best for further detailing on the models as it's supported in most 3D apps. And .stl for printing.
Sending the model to an e-mail address is the obvious solution, but the ability to connect with the dropbox IOS app and upload the model to your cloud would be even more awesome! :)
