Merry Christmas! I wanted to make a unique ornament that doubles as a printer torture test. It features a sphere with a helix cut in the middle. The bottom is flat so it can print in the orientation shown.
The picture above was printed in PLA at 60% scale on an Ender 3 Pro: it's a little springy! If you see strings or rough areas after printing (you will), sandpaper until smooth.
