Here are links to two awesome papercraft models of the Curiosity rover that you can download and -- assuming you have a LOT of patience and a steady hand -- assemble. They won't be as durable as my plastic canvas ones of course but they are a lot more accurate! The one in the photo below was made by a fellow named Yogi active on the forum papermodelers.com. Reading the discussion about how this one was designed and came together is quite interesting; and of course the forum has lots of other papercraft spaceship designs for you to build! Another Curiosity rover design, by Julius Perdana, is available from paper-replika.com (download link is at very bottom of that page). I would love to build one of these but am afraid to start lest it take over my life.
