LINK is a DIY furniture system developed by Tamás Boldizsár from Hungary. It is made from three wood (plywood) parts and various 3d printed connectors which can give many different combinations of furniture pieces. I wish that design software was open sourced or at least available to public since I couldn't locate the app. Nice idea!
