The shattered shards are a set of three suspended rock formations with base and top; clear supporting rods will be needed to support the top rock of course, using the holes in the formations. These rods are not supplied, but we recommend The Clear Plastic Shop for all your clear acrylic rod needs.
The smallest top rock formation is 150mm across, with the medium 200mm and the largest a mighty 300mm (that's a foot across!), large enough to hold a huge monster or two! Of course, you could always adapt the STL files via your printer software for a smaller or larger piece.
