I put the design on paper, marked all my lengths and went to the plastics shop and got them cut to size, as I don't have many tools to work with. But now I have a problem- I did not take into account the bottom having to be 1/2" longer and wider(using 1/4") to hold the sides. Instead, it is as wide as the baffles and left and right sides at 18" and as long as the front and back pieces at 36" (total size is 36lx18wx16h) Will this be a problem or can I glue the outside of the bottom piece to the inside of the side panels? Will the structural integrity be compromised? pics of the build to come . . .
