Awesome to see more complex designs like this actually printed. The mask radiates sleek design; it definitely looks like a worthy redesign of the organic version. Only critical suggestion that I can think of would be that the two holes at the chin break up the flow of the rest of the design by a little. But honestly, that mask would sell an official set for me.
I’ve been running into problems with doing a self-MOC and was thinking of creating my own custom Calix to be 3D printed as well. I’ve really always used a custom one in my comics, anyhow. I’ll definitely be ordering this one if you guys put it up for sale on Shapeways; it’ll be great inspiration.
