Filament Lock Mini | SUNLU Filament Clip

Streamline your 3D printing setup with the FilamentLock Mini, an ultra-lightweight and efficient filament clip designed for SUNLU spools. This low-profile clip keeps your filament securely in place, preventing tangling and unwinding. Its slim design is fully compatible with AMS/AMS2 (‼️see instructions about placement below‼️), AMS Lite, and external spool holders, allowing uninterrupted filament feeding without removing the clip.

Engineered for efficiency, each clip uses only 1.1 grams of filament, making it a quick and cost-effective print for every spool in your collection.

Features:

• Ultra-Lightweight: Uses just 1.1 grams of filament, ensuring a fast and filament-efficient print.
• Perfect Fit for SUNLU spools (3rd Gen): Snaps in place, keeping filament secure and tangle-free.
• AMS & AMS Lite Compatible: Stays on the spool during printing without interfering with automated feeding systems.
• Minimalist & Durable: Slim yet strong design that won’t disrupt spool rotation.
• Tangle-Free Storage: Prevents filament from unwinding during storage and use.

Instructions:

• AMS:
  To ensure full compatibility with the AMS, attach the clip to the right side of the spool. This placement avoids interference with the guide ridges located on the bottom of the AMS unit, ensuring smooth filament feeding and uninterrupted printing performance.

   

• AMS Lite & External Spool Holder:
  The clip can be attached to either side of the spool without any issues.

Keep your filament organized and your prints hassle-free with FilamentLock Mini! 🚀

Note! These are only compatible with the 3rd Gen SUNLU filament spools starting from 2025. SUNLU spool generation comparison. My Filament locks for 2nd Gen spools can be found here.
