Dear all!

In the past I learned to create nuts and bolts with BOSL2... :-)

Now I have demand for a -in German so called "Hutmutter". Do I have to
construct it with a nut and a sphere on it's top ? Or is there a
function I did not found, looking for it??
Thanks in advance

Karl

Looking at your picture, those don't appear to be simple hemispheres. It
looks like a cylinder, with a partial sphere above it (might be less than a
hemisphere), and the top of the sphere is cut off to make a flat circle.
Shouldn't be difficult to approximate, but if there is some requirement to
get the shape exactly right you might need to either do some measurements
or look into specifications.

For what it's worth, those are called "acorn nuts" in the US (like what
squirrels eat).

BOSL2 does not currently have acorn/hutmutter nuts. My first instinct would be to take a nut() from screws.scad, attach a short tube() from shapes3d.scad to the top of it, then attach the top_half() of a sphere() to the top of that.

Something like:

include <BOSL2/std.scad>
include <BOSL2/screws.scad>
nut("M4") {
attach(TOP) tube(id=4, wall=1, h=2) {
attach(TOP) top_half() sphere(d=6);
}
}

BOSL2 does not currently have acorn/hutmutter nuts. My first instinct would be to take a `nut()` from screws.scad, attach a short `tube()` from shapes3d.scad to the top of it, then attach the `top_half()` of a `sphere()` to the top of that. Something like: include <BOSL2/std.scad> include <BOSL2/screws.scad> nut("M4") { attach(TOP) tube(id=4, wall=1, h=2) { attach(TOP) top_half() sphere(d=6); } } - Revar > On Jun 5, 2023, at 5:47 AM, Karl Exler <karl.exler@meinklang.cc> wrote: > > Dear all! > > In the past I learned to create nuts and bolts with BOSL2... :-) > > Now I have demand for a -in German so called "Hutmutter".

I think you need to chop off the top. I think that flat part on the top is
intentional. Otherwise, what you came up with is the same as what I
suggested. I have no idea if there are stringent specifications for the
top part though.
