Final CAD & RendersThe CAD and wiring are now fully finished, and I made a few final renders to show off the completed design. I wanted the renders to highlight the overall packaging and especially the butterfly pod, so you can see how all of the reductions, linkages, hubs, and wiring fit together.I also wanted to highlight the dead-axle hub. Unlike a live axle, the dead axle stays fixed while the wheel rotates around it on bearings. This lets the axle focus on supporting the wheel while the belt system handles the power transmission, making the hub simpler, more rigid, and easier to fit within the tight packaging.Looking back at the different iterations, the butterfly pod changed the most. It went from a simple gear-driven concept to a compact, belt-driven, double-sided system with a custom dead-axle hub that is much more robust and better suited to the final packaging.Overall, the final DT is quieter, more compact, more robust, and much more refined than the original design.
