Unfold a truncated ellipse

Hello

I would like to unfold a truncated ellipse to obtain a flat file for table cutting.

The information is as follows

Elliptical "Tube" (not closed for unfolding) section 300*150 mm - thickness 0.8 mm

The sides are truncated at 8° to the radial axis or 98° to the axial axis

No matter the length of the "Tube" we will adapt it

Thank you for your help

Good answer from @ac-cobra!

and good tutorial!

Here is a second proposal, in fact it sticks with the elipses because he considers them as a spline and he doesn't like it too much. Now I just redid the piece with the esipse but by putting another sketch on top with several arcs of a circle as it will really be designed and there it works very well and the hanger will have the right radius for the realization of this part...
