I'm probably too late now, as I didn't realize that this was trending on the screenshot page for the game, but credit where it's due, this came about because of this guide. Thank catboy princess for the guide and brigadon for asking if it would work with crates.

I made a smaller one with three crates instead of four. However, the idea was based on your design, so I decided to award you some points.

I had never thought of doing it this way. Nice one!
