I agree with fyffe555. The
80/20 software is a breeze. I comes with most, if not all, 80/20 parts...from extrusions to nuts and bolts. You select your part and snap it together to design your stuff. Once you're happy with the design, push a button and get an instant price quote from the software. You can then print or fax it to 80/20 as an order.
