I currently do not have snow to test the mold, For the sake of testing I Scaled it to 50% and used Moon Sand with good results.
The mold works the same way as the original. This is the first thing I have posted on Thingiverse, If there is a problem with the .stl files message me.
I would love to hear how well the mold works with snow, Cheers.
