Follow-Me tool gives strange result

I am trying to use Follow-Me tool to have a 6" circular shape follow a specific curve. I was expecting to get a curved tube, but what I get instead is a mess with curved surfaces and lines sticking out at the “elbows” (see attached picture). I tried cleaning it up by deleting some lines, but the mesh gets broken and whole chunks of the tube surface get deleted.
I’m sure I’m doing something wrong, but don’t know what.
Please help.
I’ve also included the model I’m working with just in case.

A couplke of things going on. Part of it is due to very short edges in the arc. The other is due to the location of the path relative to the profile. It would be better if you set the path in line with the bottom of the profile so the extrusion doesn’t get folded back on itself. Here I’ve scaled the model up and moved the path. Probably you’ll need to redraw the path to make it correct.

That did it! I don’t know why I didn’t think of that.
Thank you very much, sir.

Good deal.

FWIW, you might give some consideration to how this thing might be produced in real materials. With the tight radii at the cetner of the profile, there’d be no radius at the inside corners You can see that if you use Offset. Your original path is in blue. Offset by the radius of the profile to the inside and the outside.

Would this thing be bent to shape or fabricated from multiple pieces?

It will be molded out of plastic, so shouldn’t be a problem.
