A fun Christmas ornament that looks very different from every angle!

The silver/gold photos show the ornament printed with a 0.25mm nozzle and 0.1mm layer height. The purple/gold was printed with a 0.4mm nozzle and was mostly printed with 0.15mm layer height, but I varied the layer height in a few places to get it to slice cleaner.
I've provided my PrusaSlicer 3MF and Prusa MK3S+ GCODE for the 0.4mm version. I didn't upload my files for the 0.25mm nozzle because most people don't have a nozzle that size. I didn't want anyone to try to print those by accident and have problems.
**My finished ornament weighs about 37g. **If your slicer estimates your print will weight a lot more than mine, you might want to use my files or use them as a starting point.
If you want my 0.25mm nozzle files, just send me a message. Be sure to tell me which design you're referring to (links are great), since I have a lot of models.
While it's possible to print this as one piece, printing it as two pieces will give you a cleaner print without supports. OK, I added a tiny support for the top of the loop, but you should be able to get a good print without it. The support was easy to remove and had essentially no impact on filament use or print time, so why not? If you print this as one piece, you'll need a lot of supports.
I've provided STLs for the model as a single piece and as two pieces. Print it however you like. If you want, you can cut it with PrusaSlicer and add a connector. I chose to connect the two pieces with super glue and line them up manually.
There are a few areas that need infill either because part of a layer starts in mid air or because it's thin and needs reinforcement. However, most of the ornament needs no infill. Adding it everywhere will make it very heavy. I printed the top with no infill. The bottom has 7 small areas of infill that are roughly 7mm high in total. So, just 7mm out of 156mm need infill.
I didn't print the pieces with flat bottoms. Instead, I set Bottom to zero in those areas and increased the perimeters for about 1mm to give it enough surface area to glue. The 0.4mm nozzle version uses just 1 perimeter for most of it. A few areas have 2 perimeters for strength. I increased the perimeters for the 0.25mm nozzle for strength.
