Ponoko/Google Sketchup Contest Underway

Ponoko's promoting their recent launch of Personal Factory version 4 by joining forces with Google Sketchup on a new contest: The Ponoko 3D Printing Challenge. As far as we can tell, there are very few rules, other than:
 
produce a piece of instructional content that’s equal parts enlightening and entertaining. Each entry must be titled “How to use Google SketchUp for Ponoko 3D printing”
 
The digital entries will be judged and three awards are possible: all three winners will receive SketchUp Pro v8, a 12 month subscription to Personal Factory 4, but the first place will receive making coupons worth USD$537, whereas 2nd and 3rd place will receive USD$250 and USD$100 in coupons respectively.  
 
The contest closes on December 17th, so get started modelling right away, Sketchupers!
