Moineau Pump multi-lobe edition

thingiverse

This is a revised rendition of the 2011 Moineau Pump by emmet, with notable modifications made to the original openSCAD file to facilitate the creation of multi-lobe rotor and stator components, as outlined in this guide: http://siags.siam.org/siaggd/problems/gravesen/HypoEpi3_2.html The Moineau pump (also known as a progressing cavity pump) is a versatile tool that can be utilized for various purposes, similar to the original design, where volumetric pumping is essential. Currently, we are conducting experiments with our innovative concept for a modified extruder, enabling a 3D printer to receive plastic pellets rather than filament, and this specific type of "screw" is the only one capable of providing a precise feed of plastic (Auger screws cannot accomplish this). NOTICE: version 11 has been updated, some of the previous versions contained bugs or resulted in STL files that wouldn't work correctly; please use the current version, which has been improved and will generate accurate STL files for values of "number of lobes" ranging from 2 to 9.
