Blender
A crowd-sourced free and open source 3D creation suite; supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.

MeshMixer
Free state-of-the-art software from Autodesk for working with triangle meshes. Use it to clean up 3D scans, print 3D models, or design an object that fits something else

SketchUp
3D design and modeling software with free and pay versions; supports a wide variety of file extensions.

Tinkercad
Tinkercad is an easy, browser-based 3D design and modeling tool for all and is both part of and a successor to the Autodesk 123D family of free apps.

Wikipedia has an extensive list of 3D modeling software, some free, some not. Many of these sites also contain "communities" where designers can share tips, share files and generally commiserate regarding 3D printing topics.
