First upload to thingiverse. Figured I would try my hand at the challenge. Still pretty new to 3d design, so may not be perfect. It is in a larger size so that it can be scaled down. I have printed one. Will upload pictures when I find the Christmas box =)

It is a bit large @ 100x100x110. I made it that way so that it could be scaled down to your liking.Would also angle it on the x-axis about 45 degrees to make it print easier. Would also suggest at least using a raft. Support isn't needed, but the first couple of layers are a little rough due to the overhang. I was able to print it without much problems.
