Containers for bird seed, and other bird food.

Goals:

1. Air tight to keep seeds fresh
2. Easy to refill (from LARGE sacks/buckets of seed)
3. Easy to pour seed into bird feeders

I buy large tubs/sacks of bird food, and want to decant the food into smaller containers.
I put out fresh food every other day, and I don't want to lug the large tubs/sacks every time.

Fast print, but with layer height override of 0.2mm.
