CAD Library

he following are a set of downloadable CAD files for student use. All AutoCAD files are in 2000 dxf format. If the download link fails, all files can be downloaded from links at the bottom of the page.

Bolt tap holes and clearance holes for Metric and English screws are posted in the the Little Machine Shop webpage.

More information on hole sizes can be found here.

Motor Mounting Instructions:

For detailed instructions on how to mount MAE3 motors, see the MAE3 motor mounting page.

NEW: Rack and Pinion Creation Tutorial

Note: For inventor parts files, google sites tries to use Microsoft Word as the default program. To correct this, click "save" instead of "open" in the download prompt box, and your computer should recognize the Inventor file type and change to the correct default program.
