A Snug Fit Hole
Making the hole bigger than the container only makes sense, this allows more freedom and room around it. We know that Wayne purposefully left two feet of space around the container and in front of the entrance area, to allow a full rotation for the swinging door. The real project began as soon as the container was successfully fitted. Now that you really have an idea of what Wayne has in mind, the execution of it may well inspire your own DIY projects.
