sheet metal part which wraps around a cylinder with ends overlapping to weld

Looking for a simple way to model this part.  Thin (0.004") sheet metal strip, roughly 1/2" wide, wrapped around 1.5" diameter with ends overlapping 1/8" (so not an exact cylinder).  Must be a very common use case.  How do people model this?

thanks in advance.

Part attached for reference (which doesn't yet meet the need)..

I don't have a way to open the model, but if this is like a hose clamp strap, then I would do this as a thin extrusion with a sketch of the circle and the formed ends. The thin feature avoids having to deal with the tiny .004 offset in the sketch.

Definitely model the shape you want first and then flatten.

It is exactly like a hose clamp strap - thank you - was trying to think of a similar common item.  There must be thousands of models like this - but so far I haven't found a good, simple way to address.  Note: The part that we're dealing with has a bunch of features (edge profile plus cuts) that need to be addressed in the flat pattern, then formed (rolled with overlap) and spot welded.

I would not expect a lot of faithful models. Even the mass produced straps are rarely round, instead conforming only on installation. It doesn't seem to me that many need a detailed model and instead opt for a decent place-holder.

Do I correctly detect some form of cost reduction?
