Hello,
I found that for part 4488 there seem to be various versions: 4488, 10313 and 67688.
I'm not quite sure about the codes.
In some sites 4488 and 10313 are indicated as aliases, but looking at the images of the lower part they are different, with two or three fins.
The difference between 4488 and 67688 is clearly shown in Rebrickable. The center hole doesn't seem useful for inserting parts, but it's just a material saver. For us, it's just a small aesthetic change that could be omitted.
Is it worth working on?
I am attaching some images and a first model that I have prepared.
It is not yet ready for publication and perhaps the names of the primitives should be revised a bit.
Massimo
