Useful? - Seven-segment display. Can be done, but requires a lot of controls for this. // please feel free to improve on this one, how much smoothing to apply smooth = 20; shaft_radius = 3.25; shaft_height = 13; shaft_smoothness = 20; // tweak on this script here. // for cylinder indentations, set quantity, quality, radius, height, and placement indentations_cylinder = true; smoothing_radius = 3; // Number of faces around the -x axis.
