crystal_ball

Uses spherical coordinate system to create a crystal ball.

Parameters

• radius : The radial distance r.
• theta : The azimuthal angle. It defaults to 360. It also accepts a 2 element vector. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.
• phi : The polar angle. It defaults to 180. It also accepts a 2 element vector. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.
• thickness : The thickness of the ball. Since: 2.1
• $fa, $fs, $fn : Check the circle module or the sphere module for more details. The final fragments will be a multiple of 4 to fit edges.

Examples

use <crystal_ball.scad>

crystal_ball(radius = 6);

translate([12, 0, 0]) 
	crystal_ball(
		radius = 6, 
		theta = 270,
		thickness = 1,
		$fn = 12
	);

translate([24, 0, 0]) 
	crystal_ball(
		radius = 6, 
		theta = 270,
		phi = 90,
		$fn = 12
	);    

translate([36, 0, 0]) 
	crystal_ball(
		radius = 6, 
		theta = [-30, 270],
		phi = [30, 60],
		thickness = 2
	);
