You would surely be able to see the ends of the hoses with that cutWell, I did a second opening and screwed up monumentally ... I don't know why BUT I cut it way too big than I intended. Instead of being 1/2" X 1/4" it ended up !/2" X 5/16" or a little more. Either way, it is obviously larger than the first despite not being on the same wall.
Well, this was just a "mock up" for the real one so I guess I can't complain too much. Now I'll be able to cut the doors and windows in before I assemble it all. In other words, do it properly
