Stone paving mold

A set of 3 modular 400x400mm paving molds designed to create a natural random stone pavement pattern.
The idea is to avoid the usual boring square, rectangle, or diamond paving patterns. Each mold contains a different arrangement of irregular stones:

Mold A: 20 stones
Mold B: 21 stones
Mold C: 24 stones

All three molds are designed to be fully compatible with each other. They can be placed side by side in any direction: left-right, up-down. This allows you to continue the paving pattern almost infinitely, while keeping the joints aligned and without creating obvious repeated patterns/borders.

The final result looks much more like natural stone paving rather than a repeated artificial tile pattern. By combining the three molds in different orders the pavement gets a random and organic appearance.
