There's t-junctions in the underside where the outer ring of the circular cutout meets the rectangular frame.

"There's t-junctions in the underside where the outer ring of the circular cutout meets the rectangular frame."
I don't see how this could cause any problem!
What I don't like so much is the 1-16ring11, quads and tris would do a better job with high res primitive substitution (that wouldn't match the rest of the structure that will not be substituted).
An interesting part otherwise!

I still don't see how t-junctions can cause problems either. But we have chosen to report t-junctions as problems and I can see how they're impurities in the mesh of the part and I'm just trying to be consistent here. If I need to fix t-junctions in my part because they might cause artifacts in some specific cases, then others must as well.

Also, I'm not going to vote hold for the t-junctions. So you can get this part certified without my vote as far as I'm concerned.

I'll never vote against a T-junction if I don't explicitely see the problem. Of course a t junction must have some justification: reduction of face number or improved usage of primitives.

changed origin to the one of normal 2x2 tiles

because the previous origin choice ("be like 2357.dat")
was a PITA when using this part in models.

Have you seen my suggestion about 1-16ring11?

yes, but I first wanted to finish the patterns :)

if you want you can also just improve this part as you think,
if you don't, I will come back to this :)

That video from BrickTsar show that this part should have a groove around the base.

Yes. And the cut corner wall is significantly thicker than other walls (probably to make it tangent to studs) and overlaps the stud4. Seems also that the stud4 is a tad recessed compared to cut corner, making modeling a bit easier.

here is a review/geometry testing help for you :)

please note how neatly the patterns of the 2x2cutout tile match the 1x2 tile, it took me hours to achieve that...
