Bending Strap together

Hi,

I’m trying to figure out, how to make a 3D Model out of my prototype I build from 3 wooden straps. Each straps is bent and both ends connect/overlap each other.

The only difference of the straps are the lenght. The other dimensions are pretty much the same.

I simply cant figure it out how to build it in Rhino.
