Autodesk has released a new low-end modeling software called “Autodesk 123D” that looks perfectly targeted at folks interested in stereolithography machines and “Makerbots”.   Resembling Google’s Sketchup software, it combines some of Autodesk’s own “secret sauce” in the form of assemblies and constraints that could make it a great tool for folks interested in the Home Fabrication space.

The software and a slew of free content is available for download, and it exports STL models ready for fabrication.
