The first 3D print ever of a part from the inside of the mandelbulb (as far as I know…) In raw "Strong White and flexible" and painted in gray by me… I think I will give it some clear coat too, to make it more "Spine like" The inside of the brace shows the outside of the mandelbulb spine. On my 3D printed mandelbulb bracelet you can actually see the pointy spine on the inside: http://shpws.me/opKE M3D > Fiji > Meshlab > Netfabb > Shapeways > your wrist. Use it as a brace, or just as a beautiful mathematic sculpture...
