3-in-1 Spool Insert – Weight + Silica + NFC Tag

🔥 3-IN-1 SOLUTION – Designed for any situation, anytime.

I created this model because I couldn’t find a true all-in-one solution on MakerWorld that combines spool weight, silica holder, and NFC tag mount in a single compact insert.

This design gives you everything in one module:

• ⚖ Adjustable spool weight
• 💧 Silica / desiccant chamber with ventilation holes
• 🧲 NFC tag holder
• 📏 Parametric Outer diameter

It perfectly fits Bambu reusable spools and is fully compatible with AMS / AMS Pro.

✔ Does NOT touch or interfere with AMS vertical ribs
✔ Clean clearance inside AMS
✔ Safe and smooth rotation
