Aircraft Helica - Leonardo Da Vinci - 3D printable

grabcad

This 3D printable model is based on the famous drawing of Leonardo Da Vinci - an aircraft with a helical propeller.The parts are designed with a general tolerance of 6 thou (0.15 mm).It could be manufactured by using any 3d printable technology, however i would recommend stereolithography (SLA) as a preferred manufacturing method.The model it is designed to revolve and be functional, for this you should insert in the base a rubber band as shown in the picture "rubber band placement (on the base)".For an more accurate depiction and resemblance with the Da Vinci drawing, insert two more rubber bands on the center pole to connect with the sheet support ends, as shown in the picture "rubber band placement (on the pole and sheet support)".The sheet parts may not be 3D printed, you could replace them with sheets of paper and glue them into place. Cellophane or aluminium wrapping sheets could also be used.
