Is one shell 68mm and the other 73, and you haven’t used correct spacers?

No both of our shells are 73mm. I think I'll pull it apart again and pay attention to the non-drive arm (which has the spindle attached). There could well be a spacer there but I wasn't paying attention and it just bugs me not knowing! There's certainly no play at all so I can only assume it's fine.
The carbon Next R cranks have a collar type spacer which fits the gap nicely but sod all photos or videos exist of the Aeffect cranks on the non-drive side for me to compare.

The spindle also matters here doesn't it? Might be different "Q" factor so would require another spacer?

Don’t think it’s Q. I’ve fitted for people, not used, but thought the crank had to be preloaded up flush with the BB. Not an expert with these though.

Probably missing the spacer that costs like $45 and can only be bought from WorldWide Cyclery - Its easy to misplace and forget

The inner flange of the crank looks flush against the BB though isn’t it?Gap like this?
That's my aeffect crankset. Relatively new.
I have one spacer on drive side shell. 73mm bb.

Yeah. Just looks like it steps down from that outside edge to an inner one. When the crank spins, it turns the outer seal on the bb.
You can see the lip on this diagram I stole from MTBR.

Is yours the same model @HamboCairns ? That does look too far out. But the crank arm is different to mine.

Mine's an Aeffect R.

I think I'll pull it apart and give it a harder knock into the shell. Wouldn't the cinch system pull the left side in as far as it will go?

If you grab the drive side can you pull it towards you to close up the gap on the non drive side?
Does it flop around? No? Don't fuck with it. Those adjustable collars are the worst solution eever to a problem that exists because of poor engineering.

I'll be honest. I had mine apart 4 or 5 times when installing it. Second guessing the number of shell spacers on drive side. Even though instructions said 73mm she'll needs one on DS and zero on NDS. It just kept looking a bit wrong. In the end I just followed instructions and then left it.
The cinch is how your chainring installs.
The "system" you talk of is just the 61 full grown Issac Newtons you need to install that bolt. I had to add an extension to my 8mm hex, and I still don't know I got there. Then you look at the thing and think 'fuck - maybe it's not close enough to the bb shell...'.
So I agree with Dales. If it doesn't push from side to side like MattyP suggests. And it spins ok... Leave gud enuf alone.

Yup doesn't pull, doesn't play, spins nicely.
The creak appears to be coming from the frame itself or maybe the cables rubbing very minutely against the frame.
I don't see a gap? Looks like the stepped down diameter spacer (or whatever it is) presses against the inner race of the bearing?

Well that's ok then! I just happened to see my son's left crank arm and that looks almost flush with the bottom bracket similar to this -
