Gravity sorting trays set

This is a set of modular, stackable, packable and configurable trays for sorting and storing items.

These can be used to quickly sort a bunch of items. Just stack various gravity trays, with different filters, pour the items in the top one, and shake them a bit.
Three types of filters are provided and a blind plate, for the bottom tray, to catch everything. 
You can also use the blind plate to create your custom filter.

These can also be used as a tall storage box, by using the blind plate for the bottom tray and just add walls, to make it as tall as you want.
