## What it is
The Enraged Rabbit Project adds multimaterial (multi-filament) printing capabilities to Klipper-based 3D printers, primarily VORON machines, via the ERCF (Enraged Rabbit Carrot Feeder) hardware and companion Klipper macros plus a Python module. It includes assembly manuals, BOMs, STL/STEP files, and setup/calibration tooling.

## Use cases
- add multimaterial printing to a VORON 3D printer
- build a filament multi-material unit (MMU) for Klipper
- print with multiple colors or filament types on a single direct-drive toolhead
- set up and calibrate the ERCF carrot feeder
- adapt an MMU to any Klipper-running 3D printer
- find STL files, BOM, and assembly manual for a DIY filament feeder

## When to choose
- you run Klipper firmware on your 3D printer and want multi-filament printing
- you own or plan to build a VORON printer and want a proven open-source MMU design
- you want complete open-source hardware documentation including BOM, STLs, and STEP files
- you are comfortable assembling mechanical hardware and tuning macros

## When to avoid
- your printer runs Marlin or another non-Klipper firmware without adaptation effort
- you want a plug-and-play commercial MMU with vendor support
- you are not willing to assemble, calibrate, and troubleshoot DIY hardware
- you need a software-only solution without physical hardware
