These snowflake ornaments rock. I used Creality Transparent PETG filament to print them. Set the layer height to .28, and printed them all on the same build plate. The petg is strong, the hole for the hook is open, and the surface pattern I applied on the top (concentric) gives them an extra reflective texture. These will make excellent tree ornaments and will last forever. I think they would also look awesome with a white metallic sheen PLA.
