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.

You guys are awesome!

That gives me a lot to digest.

I haven't expected that it would go so much into the nitty gritty, But
that's good so.

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

Fred

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...
