Modular Filament Spool Roller (Dual-Size Compatibility)

Enhance your 3D printing setup with this robust, smooth-rolling filament holder. Designed for reliability and flexibility, this tray features a unique dual-groove system to prevent spool slipping and a modular design for easy expansion.

Key Features

• Dual-Size Support: Specifically engineered with anti-slip ridges (ribs) to perfectly fit both 200mm and 195mm diameter spools.
• Ultra-Smooth Rotation: Utilizes two 20mm diameter rollers equipped with standard 608 bearings, ensuring minimal friction and preventing extruder tension issues.
• Modular & Expandable: Each unit includes 10mm alignment pins (chốt định vị), allowing you to securely snap multiple trays together to organize your entire filament collection.
• Anti-Slip Design: Integrated side guides and internal ridges keep the spool centered and prevent it from "walking" off the rollers during long prints.
