These tiny snowflake ornaments are about 25mm across and were generated with the Snowflake Machine.
The models are optimized for printing on an Ultimaker 2 with ABS and the standard .4mm nozzle, at .1mm layer height. If you want snowflake ornaments that are already tested and ready to go, then print these.
But it's much more fun to go make your own, so go do that at the Snowflake Machine! For 25mm snowflakes, set the "Target Diameter" to 25 in the "Global Size Settings". For this size you'll have to reduce to 4-5 steps and keep the thickness of the strands down by setting low values for "fat" and "organic".
