Concrete wave breakers

Concrete wave breakers include Dolos, Core-loc and Tetrapod models. Tetrapod files are located within the "Concrete obstacles" folder I uploaded earlier, which requires DIN912 M2.5x8 screws to assemble the mould pieces. The structures are cast in concrete. To correctly assemble Dolos STLs, they need to be mirrored, as illustrated by the assembly picture for clarification purposes.
