Where do I start?
Hi William,
Have tried to follow your advice and feel ashamed that I failed.
I tried again and again and used OpenSCAD, FreeCAD, 123D Design and
LibreCAD.
Of course I also downloaded the manuals of these programs.
In LibreCAD I could make the lines and circles thicker (1.5 mm), but when I
converted the result to an STL file it only produced a flat picture, which
means that it was not in 3D.
I still don't know how to tell the program the thickness of the wire. In my
first e-mail I gave the measurements with the two pictures: the overall
length is 42 mm (NOT 33 mm), the
upper circle is 9 mm -1.5 mm thick, the middle circle is 5 mm by 1.5 mm, the
base is 10 mm long by 1.5 mm thick and the two slanted lines are 29.5 mm
long and also 1.5 mm thick.
I would be very grateful to you if you could show (teach) me how to tackle
this problem.
Please write me some program lines in OpenSCAD so that I can 3D print this
earring......
I read the messages I received in the mailing list, I did not understand a
thing with most of them, like "Translate 3 vector axis to a camera
viewpoint" or "Read a data file in an
OpenSCAD drawing file". This is not 3D for Dummies like me..... Please help
me!?
With kind regards,

Ed,
Maybe you should forget the customizer for a while.
Try this code:
a = 40;
r1 = 10;
r2 = 5;
translate([0,0,a])
difference(){
cylinder(r=r1,h=h1);
cylinder(r=r2,h=h1+1);
}
rotate(30)
cube([2,8,3]);
Paste it in editor window and press F6. Observe the image and study the
code that produce it comparing with the descriptions in the Manual of
translate, rotate, cube, cylinder, and difference.
That is what you will need for your model but with incorrect dimensions.
Modify it to achieve your target model.
There is many levels of discussion in this forum. Don't be scared with
them. I don't understand all discussion either.

Replace the code by:

Hi Ronaldo,
Sorry to bother you again...
After experimenting I got this result:
a = 32;
r1 = 4.5;
r2 = 3;
h1 = 1.5;
translate([0,a,0])
difference(){
cylinder(r=r1,h=h1);
cylinder(r=r2,h=h1+1);
}
translate([5,0,1.5])
rotate(10)
cube([1.5,29.5,1.5]);
translate([-6.5,0,-3.5])
rotate(-10)
cube([1.5,29.5,1.5]);
I begin to feel a lot better, but it is not complete yet.
The lines must touch the upper circle, now they are in front and behind it.
The bottom line must be 10 mm long x 1.5 x 1.5 wide. So, the two lines
are too far apart at the bottom.
The second circle (r1 = 2.5, r2 = 1.75) must be approx. in the middle of
the two lines.
Could you please have another look at it? Thanks again for your help!

The translate() move things around. translate(tx,ty,tz) moves tx units
along x axis, ty units along y axis and tz along the z axis. Your cube
translations are not according to the ring translation. Move the cubes up
and down to correct.
Or try this:
translate([base/2-thick,0,0])
rotate(angle)
cube([thick,29.5,h1]);
translate([-base/2,0,0])
rotate(-angle)
cube([thick,29.5,h1]);
with appropriate values.
