Cobblestone Mold

This is a pattern for molding cobblestones from various materials.
The results are 5x5x5mm cubes which can be used for making pavements for scale modeling.
-You should use those air drying putties for the stones, or something similar.
-To get the cobblestones out of the mold, use a long and thin object and push them out. Use something like a wooden stick. It should not be something pointy rather something that is almost as wide as the mold for a single stone, otherwise the sones can break app
