Closed Spiral Christmas Ball 2025

You can scale this down a lot and still get good detail. I printed it at 50% and 100% with the standard .4mm nozzle. At 50%, the loop prints cleanly, but it is very fragile.

At 100%, I used 2 perimeters for roughly the first 7mm and the last 18mm. In between, I just used 1 perimeter. I did the same at 50%, (2 perimeters for the 3.5mm at the bottom & 9mm at the top). Use the classic perimeter generator. It's cleaner for geometric designs like this.

I tried it at 100% with and without infill. Infill is a lot better. I used 10% lightning and the final ornament was still under 20g. at 50%, I didn't need infill.

I usually print the outer perimeter slower than the default speed for my printer to get a clean, detailed print.

I've provided my PrusaSlicer project file and GCODE for a Prusa MK3S+ printer.

This design lends itself well to multi-color printing. I just don't have a printer that can print that way. For those of you who do, I created a PrusaSlicer project file using a Core One with MMU as the printer, and added to it three multi color versions of the ball - 2 versions of the ball in 2 colors and 1 in 3 colors. If you print this in multi-color, please post a make!
