Cardboard Fastener (threaded)

This is a "screw" used for fastening cardboard together. Shown with thing:1034229, a single-print hinge.

It may or may not be compatible with the Makedo "Scru" ecosystem, I've never seen a scru (or other makedo product) in person for comparison. It does work with thingiverse creations like a [tool to drive them](http://www.thingiverse.com/thing:974158), a [hinge](http://www.thingiverse.com/thing:1034229) and some [brackets](http://www.thingiverse.com/thing:955809).

I had hoped that the knurled version would be feasible to drive without the "wrench" part, but it was disappointing in that respect. I kept the design anyway, but you'll probably want to print the non-knurled version and drive it with thing:974158.

Check out the remixes! Multiple lengths, tweaked geometries, even one that is Lego Technic compatible (!!).
