I am trying to model a burger box. I used a plane and extrude it for each side. After this was done, I fold the edges to fold the box. As you can see in the image below, it doesn't came perfect out of the box. I think the problem is that the angles of the beveled edges are not the same.
I start all over again, but thought maybe there are some good tips how to achieve a correct burger box. Especially for the angled corners as they should be aligned correctly to each side.
