Samurai Demon 3D Models: Oni Masks and Katana STL
This collection gathers 3D printing projects built around samurai and oni themes: wearable masks and half-masks, helmets, sword props, decorative panels and dark fantasy figures. It is useful if you want a costume piece or a display object and need to compare how different authors split, scale and orient their files. Most entries are STL meshes meant for a resin or filament 3D printer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness.

How this collection is put together
Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

«Samurai Demon 3D Models: Oni Masks and Katana STL»
The masks divide into two groups. Some cover the whole face and read as helmets or armored heads, while others are half-masks that leave the mouth or one side open, and a few are purely ornamental pieces with dense surface detail. Sword props follow a similar split: some are static display blades, others are built from segments so a long shape fits a smaller build volume. Figure-style entries, such as demon commanders, are usually multi-part and closer to a miniature than a costume accessory.
Before printing, open the author's page and read what is listed there: overall dimensions and scale, how many separate parts the model has and how they join, whether the author used supports, and which material and layer height the photos come from. Look at pictures of finished prints rather than renders, since thin mask edges and long blade sections behave differently in resin and in filament. For anything you plan to wear, check the wall thickness and the strap or mounting points the author describes.
Search results for this theme vary in wording, so try several terms: oni, hannya, kabuto, mempo, half mask, wearable mask, helmet, katana, tanto, wall panel, hueforge, dark fantasy. Combining a subject word with a format word, such as oni mask or samurai helmet, narrows the list faster than a single broad term. Related topics like Japanese armor, yokai, and cosplay props often surface models that the main phrase misses.
If you want a different style, look at the tags and related models on the pages you already like; authors working in this theme tend to publish several pieces in the same visual language. Filtering by file format, part count or print orientation helps when you are choosing between similar masks. Sorting by newest can be useful on a live collection, since new entries are added over time.
