Quasi Knurled Ring

A ring I'm uploading in a "thing a day" hurry

I'll try to find some time to polish and adjust few flaws, print, post pics,...

...or... finally not :(

This thing is an good example of "why I don't like the 'work in progress' status", it has been like that for one year !

I'm just unchecking the wip and changing the license (why did I use a "non commercial" license???).
