Seed Sieve Parametric

I like to save my seeds, so I needed to have a way to separate the seeds from the crud. By printing on glass, and using the smooth face up, there is a glass smooth face for the seeds to travel over, and not get stuck into rough top face.
Clip in, interchangeable sieve discs make for a very easy and cheap way to get just the size needed to separate seeds from dirt and leaves etc.
