Welcome to Smart Rewinder
The innovative Smart Rewinder system is engineered to seamlessly integrate with any Prusa 3D printer equipped with the MMU3 — eliminating the need for a buffer entirely.
By intelligently responding to filament movement in real time, the system actively adjusts spool rotation in the optimal direction. This prevents unwanted tension and back pressure on the filament, ensuring smooth, consistent feeding throughout the printing process.
The result: more reliable tip forming, cleaner filament changes, and significantly improved multi-material performance—so you can focus on printing, not troubleshooting.

FITS SEAMLESS INTO OUR CORE CUBE DESIGN
The system can be used as a standalone solution, but its modular design also allows seamless integration into our CORE CUBE filament storage system (and other setups), supporting up to five connected rewinders.
In this configuration, it can be further enhanced with features like integrated LED lighting and filament drying — creating a fully optimized filament management system.
