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 but I’ve optimized it so it’s much lower than that. Central part is from Emmet's cube. Print 4 big ones and 4 small, they all fit onto bed very well.  The result is mesmerizing! 

Enjoy printing.
