So I suck at building and thought I had everything measured out perfectly..... But when I put in the tub to house the rats the entire rack wasn't wide enough so I thought the only way to widen it without re-building every level was to put in a "spacer" I used 2x2s for everything and then I used 3 in wood screws... For spacers I used 1/4 inch piece of PVC pipe... this is the final product... Whats everyone's take on it being sturdy? it seems sturdy with no weight or anything on it....
