Cord Guide that hangs on a bed's leg

Tired of tripping over a cord that runs along the edge of the bed? I made this to keep the cord for an electric blanket from sneaking out. It takes advantage of the wedge shape of the bed frame's wheel mount. The OpenSCAD file has a place to hang a 2.5mm x 5mm two-conductor cord, but you could easily adapt it for anything that you want to fit in it. The STL has two sizes, since I wasn't sure which would fit my wheel mount.
