Parametric Can Lid

Designed this around LUVSOME cat food cans since we were only feeding half of one at a time to our porch cat. Should work as is for a number of other brands I suspect, and since it's parametric, it can easily be customized if not. As currently configured in the SCAD file and in the last STL file, it seals by the angled surface making contact with the lip, which makes it easier to remove, while the 0.4 version seals to the can body, with a negative clearance, so seals more tightly, but is much more difficult to put on/off.
