About this 3D model

So, I designed and made this ornament for a contest at my local 3D-printing group meeting last month (and won an MBI Dynamo kit!). Christmas is unfortunately over for this season, but thought I'd share it with the world anyway. Note: of the 4 top/bottom pieces, the two taller ones are both for the top. You should be able to tell the orientation by looking at the curvature.
