Tripod quick release plate

I was working with uski's Tripod quick release plate, but the Sunpak 5400DLX tripod has two little tabs inside, such that the plate needs to be notched on two sides. I've included the OpenSCAD file so you can change the size of the plate and of the notch, just like uski did.

Be sure to read uski's description, particularly about printing upside-down (there's a hollow underneath for the screw head).
