Thanks to DiMarzio for creating this amazing sculpt of Castle Grayskull. It truly is a masterpiece and I have much respect for this design. I needed to remix this as a single printable hallow piece for my fish tank and I will say it was not the easiest thing I have done. I took lots of time to learn MeshMixer and wow was it more difficult than I was expecting, but hopefully well worth the work. I will post finished pictures of my fish tank when completed.
