Your description is not clear. At first I read it as a cylinder sitting on top of a cube.
Then you talk about a circular shape on the top.
I can't visualize it
Are there two questions here ?
I wish I can upload a photo. visualize it like a round metal cake pan on top of a metal box That the only way I can describe it.
