Food Hopper for a wire lid

So I need a hopper for my mouse tanks, they are 10gallon with a wire lid. Does anyone know of hoppers I could buy at a store? Or would it be better to make my own hopper such as the ASF hopper that is posted in the DIY section on here?

I'd save myself some money and just get the hardware cloth and make my own. If you're not into the DIY, I found the LIXIT bottles w/the little black cups works good for the "Becky's mix" and I'm sure you could get them to work for lab blocks too....just not much volume-wise.
