Filament Spool Guide & Anti-Tangle (Multi-Spool)

This simple yet effective filament spool guide system is designed to reduce tangling and improve filament feeding during printing.
It works especially well for side-by-side multi-spool storage setups, including Bambu Lab A1 Mini with AMS Lite or external spool holders.

The design features:

• Smooth PTFE routing – Keeps filament aligned from spool to extruder.
• Vertical guide bracket – Prevents filament from looping or snagging on neighbouring spools.
• Low-friction feed – Ensures consistent extrusion without extra drag.
• Multi-spool friendly – Works with standard 1kg filament reels and cardboard/plastic spool types.
• Printed in PETG or PLA+ for strength.
• Use PTFE tube inserts for smooth feeding.
• Mount bracket securely on your spool rack

Benefits

• Greatly reduces cross-spool tangling.
• Helps prevent filament grinding and under-extrusion.
• Compatible with dry boxes and external spool racks.
• Compact design that fits most setups without modification.

I am using PTFE Tube Connector with PC4-M10 Fittings along with this Adapter to reduce Tangling during prints. Tried many others but not working until i tried this model. So far so good! I am not using for all spools but more for those regular ones which always get tangled.
