This frees up spare spools and helps keep your workspace tidy Built-in Filament Clip: The integrated filament clip holds the loose end securely in place, helping prevent unwinding and tangling while keeping each spool organised and ready for the next print Reuse One spool, Switch Freely: Designed for repeated use with refill filament, the reusable spool supports flexible changes between colours and materials across everyday 3D printing projects Colour and Material at A Glance: Use the colour card system to identify the material and colour fitted to each spool. It helps reduce mix-ups when managing several refill filaments at the same time
