How to add a thickness to a 3d mesh shell?

Hello, im kinda new to Fusion so there might be a specific command on this one, i just couldnt find a solution anywhere on the internet.  The only thing i´ve done with the model itself was plane-cutting and rotating it. The meaning of the head was that it would be a nice popcorn holder, of course the hole shown on the image will be filled, it´s just for a reference.

Try Autodesk MeshMixer.

Oh, okay, saw a lot of answers like this in the forum but though it could be fixed somehow easier, but thanks though 🙂
