Copper Hopper
by pcal43
With Copper Hopper, a hopper can be set to hold and move only a chosen item, which removes the need for large item sorting builds.
What it does
Copper Hopper adds a hopper variant that acts as an item filter. Placing an item in one of its regular slots sets a filter: that item stays in the hopper and is never pulled or pushed out, and the hopper accepts only items of that type. Up to five slots can be set, one per slot.
The block works like a regular hopper except for filtering and for how it handles chained hoppers. Players can build simple sorting without long chains of hoppers and sorters, and the vanilla look of the hopper is kept. Copper Hopper requires Fabric API and is published for Fabric and NeoForge across the game versions 1.19 – 26.3. The server and every player need the mod installed. The code is open source under the MIT License.
Key features
Item filter per slot
Each regular hopper slot can hold one filter item, for up to five filters per hopper.
Stackable and unstackable items
Filters work on both stackable and unstackable items, with one caution noted in the FAQ.
Copper Hopper Minecarts
Minecarts carrying the filtering hopper are craftable, so the behavior can move with a cart.

Who it’s for: Players building item storage, sorting lines or farms on Fabric or NeoForge, on single-player worlds and servers that run the mod on both sides.

What the author says
Copper Hopper adds a new kind of Hopper that filters the items to get pulled and pushed. They save you the tedium of building gigantic item sorters while retaining a Vanilla Minecraft spirit. Just put an item in one of the regular hopper slots to "set" a filter. That item will never be pulled or pushed out of the…
