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

[MikeLockwood]

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.

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?

Definitely model the shape you want first and then flatten.
