WTF just did something really cool. They released the CAD for backpack 00 as an open source download on their site www.wtfidea.com/wtfiles-backpack-00-open-source-cad-pattern
In addition to releasing it into the wild on a few facebook groups, they also offered $250 to the first person who uploads a public, comprehensive assembly video in an attempt to inspire those who can assemble stuff but need a little nudge with design.
No takers so far, but the CAD file has been downloaded over 400 times.
