Hello this is my Master Chief ring. http://www.shapeways.com/model/877990/master-chief-ring.html ?li=my-models&key=f482750abbce864da6da3920a64133bc I am curious if anyone can see anything that could be an issue when printed. I would also like to know if this would be safe to sell, all modelling has been done by me using various reference images. It is currently at 18mm ring size. which is fine for my personal use but if I was to sell this I would have to make additional sizes available, and quick ways to achieve that? Anyway thought I might as well ask, I am not sure if anyone would really be interested in this, but i made it for myself as a personal project and thought id see if anyone else would be interested.
