I order two other scales: 1:3 and 1:4. I put two dies (2d6) to help judging the scale. I'm also done with printing skull. I plan to mold them next. I try to sand the 1:2 but I think I will create a mold from that current print, cast it in wax. It will be much easier the sand it and adding additionnal details and it will be a great mold base for all kind of skull.
I will mold the 1:4 first.
