Is there a better way this could have been done?
I have the following snippet.
$fn = 100;
legs() thing();
module legs()
{
for (i = [0:2])
{
if (i == 0)
translate([sin(360*i/3)18, cos(360i/3)18, 0 ])
rotate([27.5,0,0]) children();
if (i == 1)
translate([sin(360i/3)18, cos(360i/3)18, 0 ])
rotate([-27.5,-27.5,0]) children();
if (i == 2)
translate([sin(360i/3)18, cos(360i/3)*18, 0 ])
rotate([-27.5,27.5,0]) children();
}
}
module thing()
{
cylinder(d=4, h=20, center=true);
translate([0,0,-10]) sphere(r=3);
}
Other than filling a 3 element array of vectors of the rotate arguments.
Is there a better way to do what I wanted done?

I think this does the same:
module legs()
{
for (i = [0:2])
rotate([0, 0, 360 * i / 3])
translate([0, 18, 0])
rotate([27.5, 0, 0])
children();
}
I.e. just place the first leg and then rotate it to three positions.

Or if you want it parametric:
legs([0,18,0],[27.5,0]) thing();
module legs(p, rot)
{
for (i = [0:120:240]) rotate(i) translate(p) rotate(rot) children();
}
Jerry, you could reduce the for-loop to this:
for (i = [0:2])
rotate([0, 0, i*120])
translate([0, 18, 0 ])
rotate([27.5, 0, 0])
children();
