Modular River for war games

Easy to print modular river for war games, I use it also to make some experiment with resins.

It's really boring when you have to 3D-print a lot of the same pieces, so I try a different technique:

1. 3D-print the piece
2. make the silicone casting mold with Prochima GLS-Pro or similar.
Wait 15 hours before to remove the model from the mold.
3. correct it, if there are bubbles at the first attempt (I exagerate the problem to show the concept), and wait again some hours for the fixes.
