Larvae Collector? Anyone?

I have just brought home two new peppermint shrimp to eat some of these
*&%^$# aptaisia's, but on looking closely, one of them is LOADED with eggs.
I realize that it may be too late now for this brood, but I am definitely
interested in trying to breed these little devils. I have read several
articles, and I believe that I'm basically ready to go, except that I can't
find any plans anywhere for the "Larvae Collector" or "Larvae Snagger"
described in this article:

I have ordered both of the books he mentions, but I am itching to build
something and get the ball rolling.... If anyone has any better plans than
the picture in the article, of even if you have these books and could just
give me a written description of how it works, I would be eternally
grateful, and so would the little shrimpies!
