Do the sides have to be flat? You could make a segmented sphere/football with seven panels.

Take a cube and grind one corner of it flat. (Dice will work....)

also a net diagram would be helpful oh.. and the shape should be regular (the values of the lengths must equal each other)

Actually, regular means that both the edges and the faces are all the same shape. But there's only nine regular polyhedra, and none of them have 7 faces.

If you only need the edges to be of the same length, one easy solution is a 5-sided prism.
