well we built a snake rack this weekend using a lot of information from posts here and friends who have built them as well. Our problem is now some of the slots are a VERY tight fit. We put in spacers while building, so I can't figure out why its such a tight fit now. Is there anything I can do to slim down my tubs so they are a hair shorter? Anyone else run into this issue or have any other ideas?

Here is Josh with the finished rack
