CAD files for robot materials

Hi everyone,

We are looking at different types of materials to build robots with this year, and we were wondering if anyone had a list of where to download CAD files for some different common options.  So far we have seen

• Tetrix: http://www.ptc.com/communities/academic-program/k12/students/first/software
• Actobotics:  https://www.servocity.com/html/actobotics1.html (at the bottom of the page, or on individual product pages. We also saw some 80/20 on there)
• AndyMark: http://www.andymark.com under "Files and documents" for individual items
• Rev Robotics: http://www.revrobotics.com/ under each individual item
• Vex: http://www.vexrobotics.com/wiki/VEXCAD 
• VexPro (versaframe): http://www.vexrobotics.com/vexpro/  and it looks like you can find them under each item or group of items.
  

Are there any others that people find useful?

Thank you,

Maddie
