still not there yet

Ah, part curl.  Looks like there's underheating of the space and that's cooling the layers too fast causing the edges to curl up.  If you have a case, use it.  If you don't and you have a way to close it, do so.  The ambient air is your enemy on the larger prints like this.  I have trouble with even small prints (with long stems like the filament valve holder) that curl up on the ends.

Acrylic and magnets can close off your case without being permanent.  I'm also going to be adding some weather-stripping to close off any draft points.  I would hate to think that I spent that long on a print only to be done in by this effect.

Otherwise, your print looks good on the lower layers.  Some banding, but otherwise kinda clean.  If you can get a more detail shot of the lower layers we can troubleshoot calibration further.

Not sure about temps, but posts have shown a relative 70C should be enough.

As for the photos, I'm seeing a little better.  They're fine resolution-wise and show enough detail.

Is this the y-axis cable guard?  I think that's what I'm looking at.  I mentioned some banding earlier and you can see it a little clearer in these images.  This may be backlash.  Try this:

and see if it helps.  Your printer should be fine to print these parts.  Mine was and my z-axis is more screwed up that your (judging from your photos).

Acetone may save the part, but you'd have to heat the plastic up a little to get flexible enough to press it down.  I'd recommend a hairdryer as this would allow you to point weld with the acetone.

The air inside a closed Soidoodle typically gets into the mid 40s celsius which is often enough.  I can get it to 65 with a heater, though there is some debate about whether you should allow the ambient to pass 50 due to the motors.  Even slapping some cardboard on all sides should give you some improvement.

That will certainly help! However, the smaller the case, the warmer the environment will be. I attached acrylic directly to the steel frame.

Are those hinges printed?
