Generate a random crystal cluster after specifying Number of Crystal points, min and max size, and tilt range. If using OpenSCAD to generate a new STL, use F6 (render), not F5, so that you can export the STL (F7)

point_num=14; tilt=15; minsize=10; maxsize=30;

cylinder(d1=maxsize*2,d2=maxsize,h=maxsize,$fn=6,center=true);

for(i=[1:100/point_num:100]){ seed=i-1; seed2=i; single_rand = rands(minsize,maxsize,1)[0]; echo(single_rand);

random_vect=rands(-1,1,3,seed); random_vect2=rands(-tilt,tilt,3,seed2); echo(random_vect2); translate(random_vect) rotate(random_vect2) point(single_rand,single_rand*2.5); }

module point(DI,HI){ cylinder(d1=DI,d2=DI1.5,h=HI.65,$fn=6); translate([0,0,HI*.65]) cylinder(d1=DI1.5,d2=0,h=HI.35,$fn=6); }
