Yeah it'll work fine without the lip. I just added that in case someone wanted to attach something to the front to keep the filters in place. I didn't find it was really needed though. If needed you could drill holes in the four corners and stretch some wire in a cross shape in the front to keep the filters in place.
I printed the front head piece yesterday. Took quite a bit longer than I thought and I needed to sleep so I cut it short at about ~80-90% of the way through at around 3AM. Took about ~8 hours to get to that point and had probably another hour or two to go. The result is that my head doesn't have any lip up front at all, but I think it will still work fine.
I'm going to also try using some cuttable carbon filter pads for an aquarium that I can get from my local PetLand for $9. Just gotta print the stand and wait for my fan to arrive from deal extreme.
Definately the largest thing I've tried printing yet on my Prusa Mendel.
No problems slicing or loading this in pronterface.
I printed it with 0.3mm layer height, PLA, 15% infill, 2 perimeters.

The cross thing is optional and can be used to prevent the filters from moving back too far. I found I didn't need it though.
The front of the head has a lip. I included this in case you wanted to design something to go infront of the filters, for whatever reason. I first thought about attaching a flexible hose to the front but decided against it (didn't need it really).
