Then make the curves shallow enough to remove star pieces but not so shallow that the corners disappear.
Hm are you sure this works? I might think that that wouldn't help any. It would be like olzing a 5x5x1 coboid let's say, but instead of making those inner parts smaller you curve the cuts in a way that the corner pieces become even smaller. That's not the idea of olzing. The idea is to create space for the corners' feet towards the center.
I am not sure but I think that curving the cuts of 1.2.2 in a way that the centers don't appear but the corners become smaller wouldn't help at all.
