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 has consumed most of my spare time over the last two months, undergone three complete design overhauls, and countless smaller iterative tweaks.
