Well” mechanism pulleys whose purpose raise water bottom well by collecting small portion rope. To artifacts, digital model detailed geometry operation mechanisms, were carried out. 3D printing, Fused Deposition Modelling technology, made physical reproduction. digitization reproduction printing represent an update traditional ways transmitting knowledge. use these new technologies makes knowledge more accessible, understandable attractive.
