Feature Thickness:
In the vertical (z) direction, features should be kept above
0.5mm thick, but ideally above 1mm. horizontally features should be thicker than 1mm or they will not print.

Wall Thickness:
Wall thicknesses should ideally be 1mm, 2mm, 3mm, etc. (rather than 1.5mm, 2.5mm, 3.5mm etc.). These thicknesses are most efficient for our nozzle sizes.
