稲荷大神の狐

I haven’t played with it. However, I can say it is based on Fedora which is a good distro and Glorious Egg roll himself, besides working at Red Hat, is the creator of the Glorious Egg Roll version of the Proton compatibility layer.

Edit: stupid button, hit before I was finished. Besides the GE proton version, he does a lot of other enhancements to make Nobara more gamer friendly so it should be a relatively good distro to use because he knows the system better than most average Linux users and so provides the enhancements out of the box for gamers that want to game.

If you know what you are doing, the enhancements can be added to Fedora easily. But if you just want to setup and play immediately, Nobara is the way to go.

Besides Blender, the only other software I could find that can handle jewelry designing would be LibreCAD.

But it only works in 2D. It does offer an isometric view function though so it could still work out if he wants to design jewelry.
