Here is a HyperCube. I did the original mesh and Chamfer in MOI3D, converted to OBJ. Imported into Maya to make it all quads. Imported into ZBrush to detail and printed at Shapeways in Black Matte Steel.
I am still working through some scaling issues, on my end. Items are printing larger than expected, something is happening after I convert to STL and upload.
Latest sculpt, it is an ouroboros ring. I sent two versions to Shapeways, now that they have a scale button, I hope that I can get more consistency in the output. I did my export in maya and used a cylinder to generate inner and out diameters, then I scaled the dimensions in Shapeways to correspond to the outer diameter in the hopes that the ring size would accurate. I understand that the scaling could and should affect the relationship between inner and outer, but this is a test to see if I could get predictive prints. To be honest I am dubious they will even print. I added a Keyshot render for those interested.
