I'm the founder of TechShop (http://www.techshop.com), which is a growing chain of do-it-yourself workshops that provide members with access to a wide range of professional tools and equipment, training, and a vibrant community of creative "makers".

TechShop has a mix of high-end 3D printers such as Objet Connex multi-material printers, Up printers, and of course MakerBots.

We use Autodesk Inventor to create 3D objects, and it is incredibly easy to use.
