123D Make for Mac helps you turns 3D models into real creations. It converts any 3D STL or OBJ file into a physical objects using automatically generated 2D plans and animated assembly instructions.
There are 4 Build Techniques to 123D Make:
• Stacked - Create objects by cutting out cross sections and stacking them on top of each other. • Interlocked - Create slotted assemblies that go together even without adhesive. • Curve - Define the sweep of your interlocked slices with an editable spline for curvy shapes. • Radial - Define an axis of rotation around which interlocked slices are assembled, ideal for rounded shapes like bowls.

Finally, there's an extensive 123D Community from where you can download models and projects from users all around the world.
123D Make is aimed at serious 3D modelling professionals so it can be a bit overwhelming for beginners but for a free application, it's a very impressive package.
