If you use sphere_copies() (with cone_ang=180) instead of regular_polyhedron() , you gain more control over number of copies placed, at the cost of exact placement regularity.

Aren't SVG files flat? You can't do 3d designs, right? There is no way to map a flat pattern onto a sphere without introducing some kind of distortion. I can't tell what the pattern's symmetry is. Maybe it's icosahedral? If that were the case you could have the triangular pattern and load it as an svg, extrude it to a shape to cut, translate it to all the faces of an icosahedron and then you'd cut a (distorted) image of your original flat pattern tiling the sphere.
Code example using BOSL2, which knows the platonic (and other) solids. So if you can find the pattern you need to substitute for the "A" in the example you're off to a start.
include<BOSL2/std.scad>
include<BOSL2/polyhedra.scad>
difference(){
sphere(d=40);
sphere(d=39);
regular_polyhedron("icosahedron", d=40,draw=false)
{
linear_extrude(5)
text("A",halign="center",valign="center");
}
}

So, in the last time, beside 3D-printing a learned a lot about
WLED-project. And here is a new idea.
If I can manage to get a pattern like in the attachment (lets assume
5x5cm) in a SVG file.
How could I manage to create a sphere from it? In OpenScad of course.
Thanks a lot
Karl
