Fantasy object, perhaps a paperweight?

Free 3D printer files Fantasy object, perhaps a paperweight?, Tramgonce

3D model description

A half sphere with a block, on the sphere there is a surface with random arcs, it is a programming exercise in openscad.

3D printing settings

Printing can be a challenge, I added a quick look version in the gallery

With this openscad script

d=10;

union() {

sphere(100);

for (i=[1:25]) {

rotate(rands(0,180,1)[0],[1,0,0]) {

rotate(rands(0,180,1)[0],[0,1,0]) {

difference() {

cylinder(h=d,r=rands(100,110,1)[0]);

cylinder(h=d,r=100);

}

}

}

}

}

Next I used opensketch to cut the lower half away, and to cut the cube underneath the semisphere again in two
