Bricklink state that there's three versions of 2454. With or without a hollow stud blocker, and a third version is now in production with regular hollow studs.
Why did you choose a and b?
IMO it should be a, b and c, but OTOH I can't find any images of the version without a blocker. Does it even excist?

The new version have a logo on the inside of the hollow stud, so the s02 subfile can't include a stud primitive.

The stud blocker doesn't work well in hi-res mode. It also has unvisible surfaces, hidden on the inside.
You could use 4 x 3-16ndis around the bottom surface, and 2 x 1-8chrd on the top surface, instead.

The ridges are all too small and misplaced. The older version have ridges that block a center stud, but the new version allow a center stud.
These ridges should all touch the 2, or 3, stud configuration. There is no play between the ridges and the studs.

I don't see the point of eliminating T-junctions on the inside top surface.
I don't understand why you want to "plug the hole" with a disc primitive, in the new version, when a single big quad will do.
Remember, you should reduce the number of triangles in your files.

Lots of duplicated surfaces in -as01.
Missing edges in -bs01, along the ridges and inside the studs.

Did you inform Admin about the old file? It should become a Move to-file.

Thanks Magnus for the review. I think I addressed everything.
Also, I checked with Chris who agreed with a and b considering there is no evidence of the current official version.

If you use disc prims inside the hollow studs, they are to big.
Some of the loose edge lines could be included in different rect-prims. Use a rect.dat instead of rect2p.dat
