I modified your code a little so we can have a look at the fit:
use <threadlib/threadlib.scad>
turns = 7;
thread="G1/2-ext";
specs = thread_specs(thread);
P = specs[0]; Rrot = specs[1]; Dsupport = specs[2];
section_profile = specs[3];
H = (turns + 1) * P;
intersection() {
union() {
thread(thread, turns=turns);
difference() {
translate([0, 0, -P / 2])
cylinder(h=H, d=Dsupport, $fn=120); /* */
translate([0, 0, -P / 2 -1])
cylinder(h=H+10, d=Dsupport-3, $fn=120); /* */
}
difference() {
cylinder(h=5, d=28, $fn=6, center=true);
translate([0,0,-3.63]) tap("G1/2", turns=6);
}
}
cube(20);
}
This looks ok: I see no collisions between nut and bolt:
Thanks, that was a nice way to "debug" the situation :smiley:
I went on testing other print settings and with dynamic quality and the nut standing vertical, I got my first working result !
Hi,
Thanks for this exciting lib !
I've 3d printed (with an ender 3) some bolts with G1/2 threading using this lib and got good results, as I can fit standard gardening connectors.
Then I tried to print a nut as shown below that would fil but the result is way too tight.
Given the bolt is printed like this, am I missing something or should the solution maybe reside in better printer settings ?
