Howdy!
While this technically isn't a skin, it can go in your skin folder and it's a purely cosmetic mod so I think it counts (correct me if I'm wrong of course).
I put the crosshairs from QC:DE into their own seperate .pk3 that you can use independently of QC:DE.
Attatched to this post is a ZIP folder containing the .pk3 file along with the credits. Extract qcde_xhairs.pk3 to your skins folder to use it.

Crosshairs made by Id Software.
Crosshairs ported to Zandronum by DBThanatos.
