Set a default Filament Cost for each Material Type
In CURA LE 4.13 Beta v1.2, Users tend to not know of the filament cost calculator that is built into the materials. There should be a base value for Filament Cost and Filament Weight but also allow users to change the Filament Cost and Filament Weight if needed. This would present them with a part cost upon slicing at the lower left instead of just being $0. Review if Filament Densities are correct.
