A Simpler Construction of Moineau Pump Stator via CNC Milling Innovative design of a stator that streamlines its construction, making it easier to build and assemble using metal CNC milling machines as demonstrated in the accompanying image. By breaking down the stator into one fundamental building block, or base component, significant reductions can be achieved in its overall dimensions. This allows for the extrusion of plastic at 180 degrees Celsius or higher using desktop 3D printers, while also enabling precise control over the positive displacement of viscous materials from plastic PET bottles. Our revised stator design is characterized by ease of assembly and cleaning, making it an attractive alternative to traditional designs. For further details on this novel approach, please refer to: https://doi.org/10.1016/j.addma.2017.08.015 (a work in progress). These STL prototype files provided here were utilized in the testing of our simplified stator within a 2:1 Moineau's progressing cavity pump, as showcased in this video: https://www.youtube.com/watch?v=eUtr9IWUHSU
