Rug Corner Support

Remix of https://www.thingiverse.com/thing:20983

I remixed this to fit my rug. This measures 180mm in length on each side. Our rug was very curled.

Update: I reprinted this, but made the thickness 3mm instead of the 2mm in my original design. The thicker version is stronger so far, but it does add a bit of a lip to the rug, which is less than ideal.
