Really? I've never seen someone post a DIY claiming they thought up a way to make a plastc 4 tub rack that could hold 4 Iris tubs. That's because there is already a guy who makes and sells them. I've posted cooler incubator DIYs and rack DIYs, among a few others. The issue is you ripping off a member's work and getting caught trying to pass it off as your own clever idea. When you're older, if you ever do come up with an original thought, and invest your time and money into seeing it through, you'll understand why I think your post is ridiculous.
