Just finished up this new rack. It's the first I've built and I'm pretty happy with it. The blue that you see in the background is the lids to the big tubs, I used them as the back stopper so the tubs don't slide out the back. Best part, they were free with the tubs haha. Moved it out to the rodent room and it has it's first occupants already. Now I just have to make one of these with 1/4" mesh for my mice and ASFs
