Signs of the zodiac… aquarius! It's a bucket of water!

This can be scaled easily but make sure you pay attention to the value of the Z axis.  If you have X/Y/Z constrained it can become very thick.   You will also need to go into each layer and adjust the height on the Z if you rescale and change the overall thickness of the mandala.  (I.E. if you make the mandala 16mm thick you would need layer 1 to be at height 0mm, layer 2 at 4mm, layer 3 at 8mm and layer 4 at 12mm)
