I need a new enclosure for my 64. Suggestions?

So i picked up a 64 grid (sans enclosure) a few years back when tehn hosted the yard sale. Most of the complete models were either sold or out of my price range so i grabbed the naked 64 and fashioned a simple lego case for it. Well, few years later after a lot of traveling and button smashing the structural integrity of the lego case has finally given in to time. Any suggestions on what i could use? I’d just make another lego one but I’m looking for something different. Thanks guys!
