Variable Density Bottle Opener

-Added lobe above corner where stress cracks and failures were found in original (15-20% infill).
-Subtracted round hole on end of handle
-Subtracted small paths through area of maximum stress (really addition of material when printing with < 100% infill).

The 1 x 1 mm cuts though the jaw and lobe actually add more material to those areas because the slicer sees them as surface. Therefore they get made as such and end up being much thicker there than just infill (see images of slicer sections).
Sure, you can print the whole thing solid but if you are making a lot of them its nice to go fast and use just the material you have to.

Works with low infill and possibly hollow.
