We made it a priority for this model to be accessible to a range of printers, so we had to make some compromises. The maximum size is limited by the size of 3D printer beds, while the minimum size is limited by printability. The largest pieces of the model require a printer that has a print volume of 240mm x 200mm and at least 80mm high, with 0.2mm layer (z resolution) minimum. This project requires a large number of parts that must fit into one another with fairly tight tolerances.
