This may look impossible to print, but I've made it very easy by including a version with built-in supports.

I've printed this with both 0.4mm and 0.8mm walls. Both printed really well and resulted in an extremely light ornament. Pictured above is the 0.4mm version printed in Sunlu Clear PLA at 0.1mm layer thickness. Printing took about 4 hours.

With the version that has the supports built-in, you need no other supports, no raft, no brim, and no infill.

You can scale the print up or down as much as you like. At 100%, the final ornament is about 150mm high and 25mm wide. The real challenge with printing it smaller is the star-shaped loop at the top. If you print too hot or you don't have sufficient cooling, then the loop will melt as it prints. I print at 185 C.
