It's a scorpion, they are creepy and stingy but some people were born under this sign so it is what it is.

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)
