Wall Coil Support

🛠️ Wall Spool Holder with PTFE Guide (A1/A1 Mini Compatible)

Welcome! If you are looking for a way to free up desk space and ensure that your filament flows towards the printer without the slightest friction, this is the model for you.

This project was born from the need for an external spool holder that is solid but also smart, leveraging the high-quality hardware already present in the Bambu Lab ecosystem.

💡 The Brilliant Idea: A1 Hub Integration

Unlike normal 3D Printed supports, this model is specifically designed to house the original PTFE hub (PTFE Coupler/Hub) of the Bambu Lab A1 or A1 Mini.

Why this choice?

1. Perfect Rotation: The original hub has a fluid rotation mechanism that prevents the tube from twisting.
2. Secure Grip: It keeps the PTFE tube firmly in place, preventing it from detaching during fast retractions.
3. Zero Friction: Filament bending is managed by the tube, reducing stress on the extruder.

✨ Key Features

• 🚀 Space-Saving Design: Perfect for mounting spools on the wall above or next to the printer.
• 🔄 Universal Compatibility: The pin is sized to accommodate most 1kg spools (eSUN, Sunlu, Bambu Lab, etc.).
• 💪 Reinforced Structure: Designed to hold weight without bending over time.
• 🔧 Easy Installation: Only two screws are needed for wall mounting, and the hub snaps into the upper housing.
