How can I create an option to have the top faces be closed or open in an scad object? I know I can change *ID=0* but that causes the length to change. I want the same length and build of the object I just want to create an option to have the top and bottom faces to be open or close. The scad library file can be found here. Scad File <https://www.thingiverse.com/thing:3100539/files> use <SnapConnectorLibrary.scad> annularMale(length=10, ID=4.0, OD=4.5, baseRatio=1.35, toothDistanceFromEnd=0, toothMinWallThickness=0.5, tooth="ridge", toothLength=1.5,toothHeight=0.3, baseRelief=true, reliefRadius = 1, ridgeToothRatio = 0.75, toothOut = false); I also created a stackoverflow question with images. https://stackoverflow.com/questions/65463014/closing-hole-in-top-and-bottom-of-scad-object -- ----- "There are two modes of being those in bliss and those seeking bliss, may each step you take and each thought you make be made in a mindful and blissful state."
