Multi-row Rat racks?

Does anybody know of anywhere with instructions for a rack that is 3 or 4 across? The ones we've been able to find are all single racks, 6 or 7 high.

If nobody has actual instructions but has done a wider rack could you tell us what differences there are?

Thanks!

This one is the plans we used for our maternity rack. We just upped the size bins to extra large kitty litter pans. You can substitute those with the extra small concrete tub size. Those are like 20 by 16 or something. Found them at Menards.

Ours is 2 x 5. For 10 tubs, you can easily make it 4 wide and 5 tall.
