These are a set of snowflake ornaments I designed as a gift for my family. The geometric pattern they're all based on is called The Flower of Life.
For best results use the V2 of each snowflake with a layer height of 0.2mm, a 0.35mm extrusion width, and shell thickness of at least 0.7mm.
The older version I designed to print with a layer height of 0.2625mm only to discover that cura was over-riding the layer height to something that just happened to work right. However the chamfer on the top is a little too aggressive, causing some combinations of slicers, layer heights, and extrusion widths to result in "incomplete" top layers. I've fixed this in V2 to work well with 0.2mm layer height and 0.35 extrusion width.

I hope you enjoy making these for your loved ones.
