I just looked at your Z-nut trap. It has a very long and steep overhang that is not going to print in ABS without a separate print cooling fan (which I don't have). So I'll modify it by putting a couple of thin walls under each side of the overhang for support - they can be broken off afterwards.

They're artifacts from the original RRP part. I cut it down to the minimum I needed to guarantee bore positions and lengths and then built the new nut trap arm from there. I could have filled in the teardrops I guess but it just wasn't overly important to me at the time.Quote
The "teardrops" on the holes on your design would suggest an orientation that could not print (without lots and lots of support!),
If you're printing ABS I would discourage use of additional cooling. These are parts you want strong and cooling layers will weaken the bonds of the next layer. I can tell you that all these parts I printed without any additional cooling (and without generated support)Quote
I might have to baby it using a hand-held fan while those layers are printing.

Interesting. I don't have a parts cooling fan and I've printed it in ABS without supports several times.

Also, if any of the overhangs do get a bit funky on the nut trap, none of them are actually located in a place on the O2 where it matters. Just user a razor and needle file to clean up any edges that have to mate cleanly to another part.
