Yeah. I kept wondering why those indents didn’t line up right. If you do it wrong, it does “almost” fit together…but the rigid Z hits with the triangle things. I kept trying to shave a little off to try and make it work, and it just didn’t work. I got frustrated and started the whole middle assembly over again, and just happened to line up things right the second time and it worked.
