Build your own furniture with Ponoko

An octahedral modular stackable furniture piece: 8 equilateral triangular panels joined at each side and at each vertex by 24 interlocking interior connectors. The geometry allows modular stacking, along each edge (as shown in the 3rd image) or vertically panel to panel (as shown in the 4th image), for a varied array of assemblies, bookshelves, screenwalls, side tables, stools, etc.
