I made a 3d printable version of my grin sculpting.
It was quite a challenge making a hollowed version. I made a hole for the fluid but also to be able to be used with a pedestal and a metal pin and therefore I hat do build inside of this model a few supports to carry the bride of the pin hole.
My last print of this head was a mess, because I misscalculated the amount of supports therefore the print got stuck and detached himself from the print bed. I updated the version with more and thicker supports, but now I have to cleanup a few areas before the color wash.
The overall print time was 6h, the size is ca 10 cm height.
