# 3D Printing a 4,000 year old Pyramid Puzzle & a Twisted Bracelet

I use SolidWorks to design robot parts 'n kits 'n many other things.  I also use SolidWorks to teach SolidWorks!

3D Printing a 4,000 year old Pyramid Puzzle ... this lesson will take you through the most basic starter lessons of SolidWorks to get you started designing your own neat stuff.  The 2-Piece Pyramid Puzzle is as old as the pyramids themselves and as intriguing as the puzzle is when you first hand it to your friend learning how to make it opens a new world on investigation into 3D objects of all types.

The steps are all in the video for an A/V reference making learning SolidWorks extremely easy as well as how to design the pyramid part;  http://www.youtube.com/watch?feature=player_embedded&v=naM6atlC-Ak  For a higher resolution version; http://www.brainless.org/MultiMedia/Robotics/Video/Pyramid1Fixed1080p.wmv
