Huge hit!   I made a bunch of red ones and green ones.  My wife gave some out at our annual neighborhood ornament exchange and they were a huge hit!

Thank you!

(Used Cura to slice;  0.2mm layer height, 0.4mm wall (i.e. one layer), 10% infill.   Result is super-light, surprisingly strong, and looks great! Especially the translucent with a tree light in the middle!)
Ran it on slic3r 0.9.7 - upgrade if you're still on 0.9.5 or 6 - with .4mm layers, .53 mm width, 3 perimeters, and 3 top / 3 bottom in translucent PLA.  Probably could have gotten away with 2 perimeters..

Instructions

I really like the Koch snowflake - it is a very balanced shape that always strikes me as being quite festive. Here, I have punched the snowflake through the heart of a sphere and added a hanger to make a Christmas ornament.

It prints out very well on my Ultimaker with no fill. It needs a wall thickness of about 0.8mm to give it some mechanical strength, but still keep it quite light. It does not need any support, because the hanger on the top (on the side when you print) is inset into the body of the sphere sufficiently to make the slight overhang very manageable for most printers. Similarly, because of the truncated Snowflake faces, the overhang on the sphere is very small.

This is a derivative of Koch Snowflake Vase 1. If you want to play about with the SCAD file, you will need to also download Koch Snowflake Vase 1 to get my Koch Snowflake library.

Enjoy!
