Seed Zipper (separator) – Bộ tách hạt tự động

This was designed with a large format printer in mind and MAY NOT WORK IF SCALED DOWN (i'm not 100% sure though, let me know if you try it and i'll update description). THIS MODEL IS 361mm x 396mm

This requires both a shop vac and a piece of plexiglass (or cardboard and tape in a pinch however you won't be able to see separation to adjust airflow). The plexiglass I used was a piece of .0625in cut to shape. I did have other attachments however I lost them with my harddrive dying last year and this is the only file I have leftover. I figured it'd be better to upload what I have and it maybe be useful to someone instead of them having to make everything from scratch which was very annoying as a newbie at cad. I have tested the design with my first feminized reversal harvest (about 3000 seeds total which isn't too bad for a first timer!) and this saved me more than likely hours of sifting. It still definitely isn't perfect and would benefit from a good airflow restricting attachment to dial in the airflow.
