Hello,
as part of my learning, I want to make a round screw container (see
image attached).
It supposed to be a round container with a middle section (small
circle), 6 segments arranged around around it (60^o each)
and a outer circle as the outer edge.
I'm struggling now while creating the segment walls inside, around the
inner circle.
I will attach the code I came up with so far.
As you can see the struggle begins with the 2^nd segment which is not
properly positioned on the inner circle, 60^o away from the first^one.
My suspicion is the 2nd rotate command is going out of 'whack'.
I would appreciate f someone could point me to the correct approach to
resolve the problem.
Any help is much appreciated.
TIA

I use BOSL2’s turtle function for things like this.

I didn't fix your Z displacement errors (exercise for the student), but
here's how to array objects around a circle/cylinder:
module obj2() {
for (i = [0:5]) {
rotate([0,0,i*60]) translate([radius1-0.005, 0, 0])
cube([radius2-radius1, wall, height2], center = false);
}
};

I think this is caused by first rotating and translating after
that. For this type of positioning, you need to translate first
and rotate in place as second step.
Also an option might be staying in 2D mostly and only extrude to
3D as last step, example below.
ciao,

$fa = 2;
$fs = 0.2;
od = 80;

}

union() {
difference() {
circle(d = od);
circle(d = od - 2 * wall);
}
for (a = [0:2])
rotate(120 * a)
square([wall, od - wall], center = true);
circle(d = id + 2 * wall);
}
circle(d = id);

based on your sketch, I thought it was something else. 🙁 Anyway,
maybe a clue within
radius1 = 15; // inner circle
radius2 = 40; // outer circle
height1 = 1; // heigth of bottom
height2 = 7; // heigth of walls
wall = 1.5;
var=45; // adjust for transition 'twixt cylinder and cone
heightcone= 60;
heightbase=60;
$fn=100;
// round base
module base(){ cylinder(d=radius2*2, h=var);
}
//hex top
module top(){
cylinder (d1=radius22,d2= radius12,$fn=6, h=60);
}
hull(){
translate([0,0,heightbase])
top();
base();
}

If anyone is interested, this is fully parametric, (in my world). It
has rounded corners in the containers, easier to get the contents, and
rounded corners on the edges. I could chamfer the base (not fillet) for
ease of printing. I may or may not add a locking, folding handle.

Hello,
as part of my learning, I want to make a round screw container (see image
attached).
It supposed to be a round container with a middle section (small circle),
6 segments arranged around around it (60o each)
and a outer circle as the outer edge.
I'm struggling now while creating the segment walls inside, around the
inner circle.
I will attach the code I came up with so far.
As you can see the struggle begins with the 2nd segment which is not
properly positioned on the inner circle, 60o away from the first one.
My suspicion is the 2nd rotate command is going out of 'whack'.
I would appreciate f someone could point me to the correct approach to
resolve the problem.
Any help is much appreciated.
TIA

This looks really wonderful Ray
Please share the code if possible

Well,with feature creep, the script is attached. It would be simple to
make them stackable, add handles/whatever. If you have a different
number of segments to the number of sides, then the wall width can in
places become too narrow for the filleting, but you can then adjust the
wall width and the fillet radius. You can have a decimal number of
segments, and one segment will be bigger than the others, but that can
also cause it to fail to render. However, there are plenty of values
that do work OK. It uses Minkowski to round edges, etc., and that can
give problems for some values, but after a few attempts you can see what
needs changing. Generally it is the top edge rounding, so you can test
it with that commented out. I've preset the $fn values within the
modules containing Minkowski to speed up the rendering, but it is still
good enough for fdm printing..
There are obvious ways in which the model script can be broken, such as
having the wall thickness high, and the number of segments high, e.g, in
attached script, change number of segments to 18, (leave other values
'as is'). I started to test for and print those 'errors', but I'm not
overly concerned with that, since for reasonable values, it seems to
work good enough.
The values in the attached script should give the following image, if
manifold rendering selected. You may need to do a preview (f5) before
the render (f6).

That looks more 10 sided than it does "round", but there is probably a
reason for that ;-) Thanks for the wonderful exemplar...

Well Raymond,
it looks like the round container I was dreaming of when I started with
the first lines of code in OpenSCAD is here.
But I have to admit, it never looked so beautiful (in my dreams) as the
container coming out of your script.
I will be now difficult for me to complete "my script" and to see the
how the result would match up with yours.
I think I don't want to experience that humiliation.
But it gives me the opportunity to learn a little bit.
Thank you very much for your contribution.
