Description

Overture - Adapter Core

Designed to only require one core adapter per spool. Only tested on Overture cores so far, but will likely work on all cardboard spool cores as they seem to all be very similar in size.

Tapered base to make it easier to press-fit into a cardboard core. Fluted ridges to make a tight fit into the cardboard, without making it impossible to remove. Space made for a filament capture-tag so the spool-end of the filament can be held securely in place while transferring spools.

Peel away one cardboard side off of the original spool (The side with the internal/central filament tag is probably best to do first). Be careful not to let the tag get loose or the spool will unravel.
Place the spool on a sturdy surface with the peeled side facing up.
The adapter has a slot to line up with the notch on the Bambu spools. Make sure slotted side of the adapter is facing up. Press fit the adapter into the spool, until the edge of the adapter is flush with cardboard core.
Poke the filament tag through the hole in the adapter to hold it in place.
Separate the Bambu reusable spool into two parts. Insert the Bambu spool section with notch onto the spool core so that the notch lines up with the adapter slot.
Holding the filament so it doesn't untangle, flip over the spool.
Remove the remaining cardboard side, insert the second Bambu spool half onto the spool core.
Turn the Bambu spool halves so they “click” and lock together.

Did not fit on my printed spools, other overture adapters however did the trick. Otherwise nice design.

I have now updated the design, it seems there was a scaling issue with the original. Hopefully it will now work.

@SadKingBilly

I didn't fit for me either. Too tight for the hub. Seeing the message about the resize I downloaded it but it has the same dimensions as the one I printed. I'd rather not print another failed version. Can anyone tell if the inside diameter changed? -skb

Doesn't fit the bambu spools (inner diameter too small) or the Overture spool center (outer diameter too large).

@adriangarside

Mk2 still doesn't work for me. It's too tight a fit onto the bambu spool - you can force it on with a *huge* amount of effort (I stood on it at one point) which probably means it's never coming off again. I have a 1mm larger version printing but I started that before I also found it was also a very tight fit into the overture cardboard spool center so I think that will fix the bambu lab fit but make the overture center fit markedly worse. Update: Scaled 1mm larger in the slicer fit pretty well to the Bambu Spool. It was still a snug fit but no longer almost impossible to get on. And it was noticeably tighter into the cardboard but not as bad as the original print was for getting onto the bambu spool so overall it was an improvement. Seeing that other comment - did I even download the mk2 version? I pulled down the 3mf and the contained stl had a different name to the loose downloadable one. Hmm, not sure what to make of this. The inner diameter of the mk2 version is ~81.105 while the other one is ~82.042. So the mk2 version is even worse? Update2: The version I was comparing to was the one I'd already scaled in size by 1mm (outside dimension) as I saved over the one I'd downloaded to persist the size change. But that also means the mk2 one is still too small an inner diameter - the scale one I printed is still a very snug fit. Update3: My scaled version came off the bambu spool relatively easily. I had to cut the cardboard inner off it though - no way it was coming off with brute force. Update4: Redownloaded the two files to compare. Both the loose mk2 stl and the one in the 3mf if you try to print directly from bambu handy come in at between 81.1mm and 81.2mm ID (measuring in F360 inserted as meshes) and overlaying them on top of each other they look identical.
