Customizer Options

Common Gotcha's 

  • You must scale things by (I think) 1.001 to properly cut out a segment of something. THIS COULD BE A MIS-SPEC. It could be 1.0001 or something else. I haven't found the exact location of where this is specified (significant digits)
    • 

  • Watch for extra commas at the end of your function calls' argument list. This could be considered common but for pythonistas it could be considered a gotcha.

Simple Examples for Quick Reference 

// a simple hollowed out cylinder; or a ring
// variables are previously defined and this is translated to become zeroed out on the z-axis (the first line)
translate([0, 0, length / 2])
difference() {
    cylinder(
        h=length,
        r=outer_radius,
        center=true
    );
    scale([1, 1, 1.001])
    cylinder(
        r = inner_radius,
        h = length,
        center = true
    );
}
