Bambu Spool and Refill Extractor

I used to hate seeing my Bambu Lab spools sitting on the shelf, half full of filament I rarely use anymore just collecting dust. And what frustrated me even more was spending 7+ hours printing new spools just to load refills. It felt like such a waste of time and filament. That’s why I designed this Spool Extractor to quickly free up those OEM spools and put them back to work.

Reclaim your spools 

This tool makes it quick and safe to remove filament from OEM Bambu Lab spools, so you can reuse the spools with your favorite refill coils, perfect for high-volume materials you use all the time.

Features:

• Snap-fit extractor for easy spool separation
• Keeps filament neatly coiled for storage or future use
• Designed for all standard Bambu Lab refills
• Can be printed with PLA or other stiff durable materials

Version without pointy edges compatible with vacuum bags is now avalable

Instructions (please do not skip steps)

Step ONE:

Print this model together with my filament clip that holds the filament to itself and not to the spool edge.   https://makerworld.com/en/models/378548-filament-clip#profileId-278517

Steo TWO:

Unwind a little over one turn of filament and rewind it in the middle of the spool, and then attach the filament clip. This step is important because if the last loop of the filament is close to the spool wall or touching it, the filament might unwind a little when the the spool is removedand affect the next steps.

Step THREE:

Remove the top half of the spool and place the bottom extractor part (the one with vertical tabs) on top of the carbord core and filament.  

Step FOUR:

The most important step! Slide the spool to the edge of the table and hold the extractor cross and spool as pictured below. Flip both together 180 degrees, place it on the table and then slowly remove your hands to let the extractor cross touch the surface. Make sure the cross never separates from the cardboard core during this step.

LAST step:

Gently remove the other half, lifting vertically. Place the top cross on top of the refill.  Grab one of the bottom cross ends from its tab and insert it into a top cross end hook. Repeat on the opposite side and then do the last two hooks.

And thats it!   the refills  can also be stacked…

Thanks for printing
