SUNLU Rainbow PLA Filament 1.75mm, 250g Spool Bundle, 3D Printer Filament | Beginner Friendly Multicolor Bundle, Fast Color Change, 4 Rolls, Rainbow 01+02+03+04Key Features

• 【More Colors for More Projects】 Multiple compact 250g mini spools provide practical amounts of different colors for small prints, multicolor models, accent parts, and test prints. Explore more colors without filling your shelf with full 1kg spools or leaving large amounts of rarely used colors behind
• 【Faster Color Changes for Smaller Prints】 Shorter color transition intervals help multiple shades appear within compact models instead of requiring an oversized print to reveal the rainbow effect. Ideal for vases, figurines, toys, decor, and creative projects where every print can feature a different color progression
• 【Neatly Wound for Reliable Feeding】 Precision winding supports smooth, consistent feeding and helps reduce snags and mid-print interruptions. Keep light tension on the filament end while loading or unloading, and secure it before storage to prevent loose loops
• 【Fits Most FDM Printers】 Designed for most 1.75mm FDM printers with external, top-mounted, or open spool holders. Each spool measures 140mm in diameter and 36mm in width, with a 53mm center hole. For Bambu Lab AMS or AMS lite, search MakerWorld for a compatible 250g spool adapter before use
