Id like to try a little experiment. I was reading the blog post about Rube Goldberg machines and I thought it would be fun to have a community built CAD machine!

The Idea is everyone adds their own mechanism to the machine. I have created the first 2 mechanisms to start. Download the files, build the next mechanism(s) and when you are done post the new files on GrabCAD. Please add a comment if you are working on the next mechanism so others don't start building then have to adapt to your new mechanism.

-I will upload files in SolidWorks 2011 and include a STEP version of the current project.
-I will accept files in any solid format (ex. IGES, STEP, X_T)
-Be as creative/elaborate as you like!
-Please do not change earlier mechanisms unless you absolutely have to.
-Have fun!
