## What it is
BoxTurtle is an open-source, modular, compact automated filament changer (AMS-style multi-material unit) for Klipper-based 3D printers, particularly VORON designs. It is a hardware project (printable parts, BOM, assembly manuals) that requires the AFC-Klipper Add-On software to operate.

## Use cases
- automatic multi-color 3d printing on klipper
- ams alternative for voron printers
- automated filament swapping during prints
- multi-material printing without manual spool changes
- filament backup and spool switching mid-print
- build your own filament changer from a bom

## When to choose
- you run a Klipper-based printer (especially VORON) and want AMS-like multi-material printing
- you want an open-source, self-sourceable or kit-available filament changer
- you want hardware designed around the AFC-Klipper Add-On ecosystem

## When to avoid
- you use a printer firmware other than Klipper (e.g., stock Bambu, Marlin, RepRapFirmware)
- you want a plug-and-play commercial unit with vendor support rather than a DIY assembly
- you are unwilling to source parts, print components, and assemble hardware yourself
