Air Column Seed Classifier

Let this infernal contraption stand as a cautionary tale about the dangers of chasing after innocent-seeming "rabbit hole" ideas.It all started with a casual "I bet I could" moment, something I thought I’d knock out in a day, or maybe a weekend. Instead, this project consumed most of my spare time over a two-month period, underwent three complete design overhauls, and countless smaller iterative tweaks. I’ve invested more hours and filament into this thing than I care to admit. And in my mind, it’s still not finished. But I’m forcing myself to let it go and call this "Version One." What is this thing?I’ve been calling it an "air column seed classifier", its purpose is to separate seeds (basil, in my case) from chaff and then classify those seeds based on quality. It’s not a new idea/concept, but the only examples I have been able to find online are large and cost thousands. How does it work?The idea behind this device is simple: high-quality, viable seed
