This is a remix of snowboard made for lucky 13 adapted for dummy 13.

I desing several models:

If you just make 1 board print the normal one for matching ankles with dummy 1.0 o dummy Beta, this need suports in the front and back.

If you need to print several boards or want better finishing, print the bending support with supports (do not remove the supports), then print the board flat sumerge the tip in hot water 70°C aprox. about 10 seconds an then lay down the board on the support, repeat with the other tip.

The original board for Luky 13 in here:
