Seed Tube with Crate

I looked everywhere but I could find nothing to hold my precious chili seeds. So I came up with the seed tube and a stackable crate to hold them, along with a custom-made [funnel](https://www.thingiverse.com/thing:1763508) to ease filling.

I suggest slicing the threaded parts with `0.1` mm layer height for better results. I'm using the variable settings wizard in Simplify3D to print the body with `0.35` mm and the threaded top and cap with `0.1` mm. That way I can print 20 bottles in 5 hours
