Problems with a half-torus
-
I wonder why that happened.
-
Well it's back and better than ever
And when it cropped up in conversation yesterday my friend told me his brother has a 3D printer, so he can print it - perfect. Just need to figure out how to make the stl file converter plugin work now. 
It came to me, you just attach the .skp file...
If anyone wants to run an eye over it for errors at the 3D printing stage I'd be much obliged -

Extra tips:
Model so the faces' fronts are 'outwards' - context-menu 'reverse'...
Depending on the Style settings the front color is generally 'off-white' and the back color 'bluish' - your faces look like 'backs'...I have reversed the face of the bell if that's what you mean TIG:
-
It's not a solid (no thickness , internal faces, ...) so you will not be able to print it with a 3d printer.

I had a quick look...your model needs to be "Solid" to be 3D printable. Right now, you have a bunch of single-face walls with no thickness that will not print. You have to actually create the desired wall thickness for it to print properly.

I see what you mean. Sort of. Until you pointed it out I thought the area under the bellmouth was solid: how can I make it solid? I just know the push/pull of Follow tool will be a nightmare...
I don't/ can't see what the internal face is that I need to delete?
-
Teig, the bottom of the bell was likely not formed when performing the follow me operation at too small of a scale.
Does the center have a hole like a donut? Assuming so, here's how I'd make the overall shape:
After you run the follow me tool, you're left with a solid that you can add the bottom holes to.

Aaaah, you have saved as 2015!
So owners of other versions can't reload your file!
It's so easy to save as V6 for a more large audience! -
Gotcha! I think! Draw the profile at the very start. I've been trying for three hours now to put an arc under the bellmouth!

I'll try again with an older version. -
Pilou,it's long past time for you to catch up to the rest of the world.

Pilou, doesn't your computer run 2015? Before I even start using some versions, I get a copy of the latest just so I can open files from others (and also to try it out some). I then back-save a file myself if I really want to play with it, using my current plugin and setup.

You could use JointPushPull plugin to thicken a curved surface, but starting with a new profile is much cleaner and probably faster.
-
I eventually got it sorted (hope), thanks to you folks. It really does look like the perfect bellmouth now - I couldn't sleep last night I was so excited
I'm at work now; I'll put the (v6) .skp up later.
-
Nice!

Nearly there...
I purged the model [Model Info > Statistics...]
I erased all guides.
I then regrouped the geometry.
It reported as a non-solid.
I suspected some un-faced edge[s] have been left hanging around...
I ran SolidSolver on it and it removed some 101 Un-faced or Coplanar edges.
Then it reported as a solid.
Simply using CleanUp would probably have made it a solid too...It is now suitable for 3d printing...
-
I know it's not sensational or a spectacular Sketchup item but it's big to me
Here it is in all its glory:It's not solid and I don't know why, its in 4506 'entities'! I'm not bothering with the vents and mounting holes now; I can do them later on the milling machine and lathe, what does it need for 3D printing?
I've added the rounded lip on the edge of the bell mouth as an afterthought but I can't get rid of the joining lines; how do erase them?

When I can figure out how to install those extensions I'll do mine then
Or do you mean I can click on it and download it from my previous post? You have facility for interactive editing then? WOW

I'm trying to work my way through that list but can't get rid of this guide. I went inside the mounting flange to try to erase it from the inside, no luck

Of course, thanks to the folk who've contributed
