Description

I got fed up of storing full size cardboard spools with only a tiny amount of filament left on them, so I've designed a small spool that fits the Bambu reusable spools in the same way as a refill.  I'd estimate the approx capacity around 350g - there is a photo showing an exact 250g in the gallery, but its admittedly not perfectly neat so you can probably do better if you try.

 

It has the following features:

a) Spool prints in two parts on a single plate within my P1S (approx 70g of filament needed).  These parts should hold together by friction fit, but I've been adding a couple of drops of super glue to be certain.

b) There is a “grip” on the inner surface to hold the end of filament without the need for either harsh bends or tape.  

c) I've included push fit tags to mark the filament type being stored - while the photos show these as a single colour in practice I print these in different colours by type to make ID even quicker.

 

Thats it really - hopefully helpful and cuts down on storage space.  I'd recommend printing in PETG, ABS or ASA as PLA might deform during a drying cycle.

is there an option to make this thinner (like half as wide)? I stack my spools horizontally so that would help me a lot. Perhaps include 2 spacers and/or make a dual sided version.

Hi - I've added an alternate half height "main spool" part and spacer to the files section - i think it'll work best with a single spacer as the locating lug is on the edge of the original reusable spool and this way the spacer can just be a tube. I've not tried this design so the spacer may need some work, but you could just print two of the mini spools and put them side by side.

I printed in PETG and definitely needed glue to hold it together. But the gap to hold the filament at the base of the roll worked great. I was even able to transfer the RFID tags from the cardboard core to this mini spool, and am very happy to have freed up my spool that came with PLA Support material 😂 This is a great idea and I will be using these to hold all the little 250g rolls of filament I got for Christmas.

Printed well and great to free up some of the spools and cut down on storage space. Already printed using 4 and planning to do more.
