I'm sorry but I don't get it: am I supposed to print ALL the files? I don't see any difference between 22 and 23, they even have the same file size. I don't know if I'm a bit too tired or if the instructions aren't that clear. I got the idea of the _B files with or without support, but for the sets, I'm not sure.

I'd really like to print this one because it looks very nice, thanks for the hard work by the way!
