// logo.scad - Basic example of module, top-level variable and $fn usage

Logo(50);

// The $fn parameter will influence all objects inside this module
// It can, optionally, be overridden when instantiating the module
module Logo(size=50, $fn=100) {
    // Temporary variables
    hole = size/2;
    cylinderHeight = size * 1.25;

    // One positive object (sphere) and three negative objects (cylinders)
    difference() {
        sphere(d=size);
        
        cylinder(d=hole, h=cylinderHeight, center=true);
        // The '#' operator highlights the object
        #rotate([90, 0, 0]) cylinder(d=hole, h=cylinderHeight, center=true);
        rotate([0, 90, 0]) cylinder(d=hole, h=cylinderHeight, center=true);
    }
}
