please create new dieline with a top and bottom seperation type.
Do you have a sample, sketch or something like that? It is not clear form the description what exactly is needed.
upper and lower pairs style to assemble
Either single or double wall, please make its possible
Although I put this into the TODO list for our dieline generator, it may take a while before this shape will be added. You can do it much faster yourself, using Illustrator and Origami (if this is an option).
Thank you. I will wait until it is added.
