Hello together,
some time ago I started 3D-printing RC-airplanes using Cura to generate the required G-codes.
The way I go is that I just build the required volume models with a CAD programm and then print them with the "Cubic Infill" and one outer perimeter to get light but strong parts. To vary the strength within a part I use overlapping volumes and assign different infill values to them.
(First the overlapping volumes, then the Infill without the outer perimeter)
The "Cubic Infill" works quite well as an internal structure for wings and such, at leas
