Spiral Christmas Ornament 3D Print, a Festive Two-Size Set

A spiral Christmas ornament 3D print is one of those small projects that makes a tree feel finished without taking over the room. The idea here is simple: take the familiar cone shape of a Christmas tree and twist it, so the surface spirals upward instead of sitting flat. That one change gives the ornament a modern look while keeping it instantly recognizable as a tree, which is why it works so well mixed in among more traditional decorations.

Printed, the ornament reads as a continuous ribbon of material winding around a central form, and the curved surfaces are what give it character. Light catches differently on a curve than on a flat facet, and that becomes especially noticeable with a filament that has some sparkle built in. The spiral detail is subtle enough not to look busy, but present enough that the ornament stands out from a plain wireframe tree shape hanging nearby.

Two sizes, and two more designs hiding in the files

The set comes in two different sizes, which means you are not stuck printing identical copies for every branch. Smaller ornaments can sit toward the top of the tree or cluster near the trunk, while the larger size works as a statement piece lower down where there is more room. Mixing the two sizes across a tree gives a more coordinated, considered look than one size repeated everywhere.

Beyond the two sizes shown in photos, there are two bonus variants included in the files. These were not photographed, so they are a bit of a surprise once you open the package and start slicing. If you print the whole set, it is worth going through all the files rather than assuming you have seen everything from the pictures alone.

Ribbon or printed hooks for hanging

Every ornament has a loop at the top, and there are two ways to use it. The straightforward option is to thread a ribbon through the loop and tie it off, which is the softer, more traditional look. White ribbon was used in the reference photos, and it pairs well with the spiral pattern without competing with it visually.

The second option is a printed hook that snaps out of its own frame as part of the file set. Once popped free, the hook attaches to the ornament’s loop and hangs on a branch the way a standard metal ornament hook would. Both methods are included so you are not left sourcing hardware separately, though ribbon tends to be the preferred finish for this particular design.

What filament works best for a spiral christmas ornament 3D print?

These ornaments were printed in Bambu Lab PLA Sparkle, in red and green, which are the two classic Christmas colors with a bit of shimmer worked into the filament itself. That sparkle is what makes the spiral grooves catch warm tree lights rather than just sitting flat and matte. It is not a required filament, and other color combinations can be used to match whatever theme you are decorating around that year, but the sparkle effect is specifically what was used for the festive look shown in the photos.

Files are provided as STL for general slicing, along with predefined 3MF profiles set up for Bambu Lab printers, so there is a direct path from file to finished ornament without having to dial in settings from scratch.

Where it fits among your other decorations

This is a small-format print, sized for a tree rather than a shelf, so it slots naturally into an existing collection of ornaments instead of asking for dedicated display space. Because two sizes and two extra variants are included, one print run can realistically dress a good portion of a tree rather than producing a single lonely piece. It also travels well as a handmade gift for anyone who already owns a 3D printer or appreciates a decoration with some thought behind its shape, since the spiral twist is distinctive enough to be a conversation starter when guests look closely at the tree.
