Modular MMS system (Poor man's AMS)

I designed this because I couldn’t find any existing MMS (Manual/Modular Material System) files that worked well with my setup. Most available designs were either incompatible, overly complex, or more expensive than necessary. This project is meant to be a simple, practical alternative that’s easy to build and customize.Each unit weighs approximately 140 grams, making it relatively low-cost to print. The design is easy to assemble, uses minimal hardware, and doesn’t require any special tools. It’s intended to be accessible while still being flexible enough for more advanced users who want to experiment.Important limitations and notes (G-code related)This is NOT a full AMS replacement.It does not function the same way as an AMS (Automatic Material System). By default, it only supports single-color layers and cannot automatically handle multiple colors within the same layer.Multi-color printing requires modified or custom G-code.Multi-color prints are possible, but only by using manually
