Mechanics
The white stained glass in the crafting recipe can be replaced with any stained glass type. This doesn't change the functionality of the block.
Item filters only transfer in one direction, which is displayed on the texture in a 'funnel' shape.
By moving an item into any one of the slots in this menu, the filter will only allow that item to transfer through it. The setting can be changed to blacklist which does the opposite, and allows all items but the ones set in the 6 slots to transfer.
The Item Check setting can also be changed between 'Lenient' and 'Strict' by clicking on the drill items below each slot. Each slot has an independent Item Check option.
Lenient item checks only match item IDs, whilst Strict item checks match all item data.
