I use these Feenwald
(FairyForest) boxes all the time and have finally finished updating them to have all of my colors (100 as of Aug 22 2011). The mesh for these boxes is now in the folder since it is no longer available.
Julsfels has redone the mesh on her site (at the link) and it has a new GUID and mapping, so it should not conflict with this one; it's also part of a repository set and awesome! However, I don't know when I'll get around to redoing these to use the new mesh. Check out her wonderful site and the other amazing things there!
