I am about to start cutting and building my rodent rack from the small size plans on Rodentracks.com. The measurements on the website call for the black mixing tubs to be 19 3/4" x 27 1/2" x 6". I bought the tubs at Lowe's. There was a small size and large size of the same tub (just like there is a large tub and small tub build on rodentracks.com). The tubs I got measure 20" x 26" x 6". It's hard to imagine they redesigned these tubs to be an inch and a half short one way and a quarter of an inch short the other way.

Do I need to make adjustments in the cuts/plan for these tubs? I'm looking for input from someone who has actually done the build before. Either that or input from someone mechanically gifted
