After printing a bunch of simple gear cubes I decided to make something special. Yesterday I found a box with celtic ornament and combined this pattern with gears.
Print time was about 14 hours with 50mm/s movements, 20% infill, 3 walls. Central part is from Emmet's cube.
Print 4 big ones and 4 smol, they all fit onto bed very well.

The result is mesmerizing!
Enjoy printing.
