Description:

This upgraded version of the Bambu Lab reusable spool holder brings a range of practical improvements aimed at usability, efficiency, and compatibility:

• Hexagon Side Pattern: Offers better visibility of remaining filament, uses less material during printing, and maintains strong structural integrity.

• Multiple Filament Slots: Features 6 pairs of holes evenly spaced around the rim — significantly more than the original's single pair — giving you more flexibility to secure filament ends.

• Filament Passthroughs: Added holes allow easy filament anchoring when re-spooling.

• Quick Alignment System: Arrows inside both parts help quickly align and snap-twist them together without guesswork.

Angled Holes (v2 Update): Rim holes are now tilted at 45° to reduce bending stress on filament ends.

• Wider Compatibility: Supports even damaged or stripped-down cardboard spools, including those with core diameters smaller than Bambu Lab’s standard size.

To assemble one complete spool, print one “narrow” and one “wide” model.

Versions:

Choose the right STL version based on your needs:

For Bambu Lab filament refills:

• Use the files under Print Files (STL) for Bambu Filament Refills.

For general re-spooling or third-party filament:

• Use Print Files (STL) for non-Bambu Filament Refills.

These models do not have the notch specific to Bambu Lab refills and are suitable for cores ≥ 81 mm.

For smaller cardboard spools (69–80 mm core diameter):

• Use the Files for smaller cardboard spools, which includes a 74|75 mm version (ideal for newer Inland cardboard spools).

Printing Instructions:

• No supports needed.

• Recommended materials: PETG, ABS, ASA, PC, PA-CF.

Note: PETG is usable but avoid high temperatures (≥85°C) in filament dryers.

• For maximum durability:

- If using strong materials (PC, PA-CF): 15% infill is enough.

- For others (like PLA, PETG): use 6 wall loops and 25% infill.

• Dryer-Safe Advice: For drying compatibility, PC or PA-CF is preferred due to their higher thermal resistance.
