Modular spool holder

🧵 Modular Spool Holder – 3D Printing This 🧩 modular holder is designed to efficiently organize the filament spools 🎨 used in 3D printing. Each module houses up to 3 standard spools, held in place by curved grooves that prevent slipping and facilitate rotation. 🔄 Modular design Expandable at will! You can join multiple modules together to create a customized structure, perfect for any workstation 🛠️. 🖨️ Easy to print The design is optimized for fast printing, without supports. Just one piece is enough to have a stable and functional support. 🎯 Compatibility Designed for 1kg spools (standard size), but thanks to the curved shape it is also compatible with slightly smaller or larger spools 📏.
