Thank you for the fast answer. I would suggest to locate the split just in the edges under the lower panels and then leaving the complete backwall with it`s entrance hole on the bottom panel. If I`ve senn the details correctly in this case the gaps wpuld be almost unvisible und it would be perfect to paint und mount fine details likes hoses. Did I understand it correctly, that you are thinking abaout splitting this only in certain materials?
Many greetings Martin
