Ninja Hoppers

A Netherite hopper behaves like a normal hopper while its filter slots are empty. Once a filter slot holds an item, the hopper accepts only items that match one of its filters. Each of the nine slots can hold a different item, so one hopper can group nine kinds of stock in a single block. The top slot is the one inventory slot above the filters, and a chest or a wooden block can sit below it as the destination.

The mod is built for late-game storage. The crafting recipe was set deliberately high, drawing partly on the materials of a standard redstone sorter, so choosing this hopper over cheaper designs is a decision made on purpose. It replaces the redstone parts usually found in storage systems. The mod is based heavily on Golden Hoppers, which is also a Fabric hopper mod for 1.16.5 and earlier releases. The author notes that a Netherite hopper is the only addition in this first release, and that more hoppers are planned.

Installation needs Fabric API on Fabric. Ninja Hoppers runs on client and server, so the server and every player need it. The files are for 1.16.5 only, and the source is released under CC0 1.0 Universal, which places the code in the public domain. The mod is incompatible with Hopper Optimizations, so that mod must be disabled while Ninja Hoppers is used.
