CFS Spool Adapter - 250g

The Creality CFS is built around 1 kg spools, so a 250 g sample spool sits loose and off-center in the bay and is prone to jamming. This is two printed halves that thread together through the small spool's own bore and carry it on a 200 mm flange — the diameter the CFS expects — so it rides centered and feeds like a full-size roll.

Two plates, one per half, and you need one of each per spool you want to run. There is a combined 3MF with both halves on it if you would rather print them in one go, and the STLs are in there for bringing your own profile.

The 3MF is the faster path — open it, pick a plate, and slice. A full print & use guide is attached to the Creality listing.

What's Included

Two Halves, One Spool

A nut half and a screw half. The screw half's hub passes up through the center of the 250 g spool, the nut half threads down onto it, and drawing the two together clamps the spool between them and centers it on the axis the CFS actually feeds from.

Two Parts, No Hardware
The halves thread into each other, so there is nothing to buy and nothing to lose. No magnets, no screws, no inserts — print the two plates and that is the whole bill of materials.

It Uses The Spool's Own Bore
The threaded hub is sized to pass through the middle of a 250 g spool, so nothing is clamped against the flanges and nothing has to grip the filament. Drop the spool on, thread the second half down, hand tight.

Centered, Not Just Held
Both flanges are conical on their inner faces, so tightening them pulls the spool onto the center rather than wherever it happened to sit. That is what takes out the wobble and the off-axis feed that causes tangles mid-print.

200 mm Across, On Purpose
That is the outside diameter of a standard 1 kg spool — the size the CFS is built around. The adapter presents the machine with the geometry it expects, so the small spool loads into a bay alongside full-size ones and needs no change to the printer at all.

Print Settings

Slice It Right

These are the settings the reference prints were made with. The 3MF carries the full profile — open it in Creality Print or any slicer that reads 3MF projects and it is ready to go. Both halves run the same way: 0.10 mm layers, 3 walls, 10% gyroid, and no supports are generated anywhere despite all the spoking.

The two plates sum into one adapter. 52.07 g and 2 h 47 m for the nut half, 64.81 g and 3 h 51 m for the screw half — 116.88 g, 6 h 38 m and about $3.50 the pair. Printing several, print several of each; the halves are not interchangeable.

The layer height is the one setting worth checking. These are printed threads, and at 0.10 mm they come off the plate turning by hand. Coarsening the layers to save time is the change most likely to leave you filing a thread that used to fit.
