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;

circle(d = id);
}
linear_extrude(height) offset(-wall) offset(wall) difference() {
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();
}

That gives me a lot to digest.

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.

A baby can be defined as an ego with a noise at one end and a smell at the other.
Your job as parents is to teach them to control all three.
My job as a grandad is to tell you how you are doing it all wrong!
