Feeder size sorting colanders?

[APailthorp]

Anyone know someone selling on line a set of size sorting colanders or grates? I want to use them to sort dubai roaches.

My experiment drilling holes in a set of plastic buckets worked kind of, but not very well and I'm not happy with the result. The holes came out too rough, and I'm wondering if anyone sells a set of reasonably priced molded plastic sorting colanders or grates.

Thanks,
-->Aaron

This looks like it might be the solution to my problem (not being able to drill nice holes in a thin plastic bucket):
Sample Assortment Aluminum 3003 Perforated Sheets, 6" x 6" Sheets (5-Pack)

I'll post again when I've gotten these, added them to containers, and have had a chance to try them out.
