Bridging Test with less material

I've created variants for 0.2 and 0.3 mm layer height. 

0.2 mm version is sliced at 3.22 grams.

0.3 mm version is sliced at 4.06 grams. 

The original BridgingTestMaterialSaving.3mf is sliced at 5.47 grams.

There are four layers above the bridge layer and only two layers at the bottom pad. 

Happy bridging!
