About this 3D model
A derivative of richardberwick's Personalized Snowflake (http://www.thingiverse.com/thing:37744) I just made the middle solid, added four posts and a top frame. You'll need richardberwick's orginal file if you want to do anything with the OpenSCAD code. A bit late... yeah. :-( But I got all caught up having fun the past few weeks and didn't have much time. :-)
