Hovering Disk For Less Perfect Surface- Frictionless Motion Experiment

thingiverse

I'm remixing fgebharts hovering disk, but his version didn't quite work for me. The disk failed to lift much and the movement was anything but smooth. I suspect this was due to imperfections in my print surface and the table or floor it rested on. The nozzle of the original design is extremely narrow, which prolongs the hover time but reduces airflow, making a smooth surface essential. To make it workable under normal classroom conditions, I widened the nozzle. Additionally, I relocated the rim that holds the balloon downward to better support its neck, resulting in greater stability and minimizing the risk of the balloon toppling over or bursting at its weakest point.
