a couple thoughts came to mind.
the inner diameter of the sphere is the target diameter.
so i added twice the wall thickness to the diameter of the first sphere.
also, if a 25mm long neck is placed on top of a 2mm thick sphere
the effective length of the neck will be 27mm. so i tried
subtracting the wall thickness from neck length for the cylinder height.
seems functional.
also, aren't variables actually constants? sorta like constant variables...
// Example: A 220Hz
$fn=100; // fragment number
sd=132.48; // sphere diameter from formula
wt=2; // wall thickness
hd=25; // sound hole diameter
nl=25; // neck length
// Sphere
difference() {
sphere(d=sd+(2*wt)); // create sphere to be hollowed
sphere(d=sd); // hollow the sphere to diameter from formula
translate([0,0,-(sd/2)-wt])cylinder(d=hd,h=wt*2); // create sound hole
}
// Neck
difference() {
translate([0,0,-nl-(sd/2)+wt])cylinder(d=hd+(2*wt),h=nl-wt);
translate([0,0,-nl-(sd/2)+wt])cylinder(d=hd,h=nl-wt);
}
Printer will print perfect...
