i made the baffle as directed on page one, but was afraid of my betta's fins getting cut and it was still pretty strong. I have the aZoo 60 (aka the palm/red sea nano) in an 8x8x8 2 gal cube.
when i was in the pet store i looked around and found exactly what i needed. the fluval chi preflilter
here is what i did
the box...

i cut it apart as you can see (one piece is already missing as I used it)

the one "side" of the chi fits the azoo perfect!

i "tucked" the filter in over the other filter media (i used the white azoo sponge and some bio filter in a bag for filter media)

all self contained...
i ALSO tried this over the output of my finnex canister 360 (mini canister that is great for 6 gal) and the water goes through it no problem but it softens the flow...
the box of 'prefilters' was $3 and 2 filters came in the box that is a TON of material (i could do 4 azoo filters)
