The only part of this print that requires supports are the posts.  The front frame printed fine without supports.   I glued the front post holders in the slots on the back of the front frame with epoxy.  Super glue will probably work as well.  Make sure you sand the post so they fit into the post holders snuggly but not to loose. Also, sand the inside edge were the nose bridge is so it's a little more rounded.  This makes it less irrirating to your nose. Have fun!!!
