A set of building blocks for making human-scale items like furniture, desks and shelving.
Use connectors to join bars and corners. Use pins to fix connections. Use caps to conceal pins and provided a finished look. Use two or four pins per connection. When using one pin per connection end, the pin leg should be in the outer hole since this is structurally stronger and creates stiffer parts.
Components are designed to be printed with no supports. For most structures, I recommend 2 shells, 2 floor and ceiling layers and 5-10% infill.
