Gear with Internal Propeller

thingiverse

I came up with this concept while tinkering on a remotely operated submarine project. The goal is to minimize drag and boost gear reduction efficiency. Two idler gears will support the gear, which will then be connected to a drive gear (the hole in the propeller gear was for testing purposes; if you need one with a slightly modified design, feel free to adjust it or ask me about it). This setup keeps no motor obstructing the airfoil created by spinning propellers. If you have any questions, please don't hesitate to reach out and be sure to share your experiences if you decide to use this model in any of your projects.
