3D models that print well and stay yours

Why we exist

The 3D-model marketplaces we knew were either too cheap (sketchy files that need 30 minutes of mesh repair before you can print) or too expensive (locked behind subscriptions, royalties, or shrink-wrap commercial restrictions that let you print one thing as a gift).

Brethof AI is the alternative: well-prepared models, transparent pricing, two clear licences, files you actually own forever. No subscriptions, no royalties, no per-print fees.

What makes our models different

• Print-tested where possible. Many models are physically printed before they go on sale. Models that have been printed are tagged on the product page so you can filter for them.
• Multiple formats included. Every model ships with GLB and OBJ. STEP, FBX, and GLTF when the source supports it. One purchase, all formats.
• Real previews. Eight high-resolution renders from different angles, plus a 6-second turntable video. No deceptive lighting tricks, no fake reflections.
• Honest dimensions. Real measurements in millimetres, polygon counts, the actual file you'll get.

How the prices work

Two licences, fixed prices, no surprises:

• $2–$5 Personal Licence — print as much as you want for yourself, your family, your hobby projects.
• $20–$30 Commercial Licence — everything in Personal, plus you can sell prints, use the model in client work, build it into commercial products, embed it in games and films.

Pay once. Lifetime access. Free updates if the model changes. No royalties on what you produce. Full details on the Licence page and the Pricing page.

The Brethof family

Brethof AI is one of four sister sites, sharing infrastructure and design system:

• brethofai.com — this site, 3D model store
• brethof.eu — 3D printing service (we print and ship physical objects)
• brethof.com — Brethof Voice Pro, professional voice software for content creators
• brethof.ai — the umbrella brand and AI research blog

If you buy a model and want it printed, brethof.eu can print and ship it across Europe. If you want to learn more about how we use AI in our design workflow, brethof.ai is where we write about it.

How we make the models

We use a combination of human design and AI-assisted generation. Every model goes through:

1. Design — concept, modelling, or AI generation, then human refinement.
2. Mesh repair — manifold check, hole filling, normal correction. The file you get is print-ready.
3. Print test when feasible — we slice it, print it, and verify it matches the renders.
4. Multi-format export — GLB and OBJ.
5. Render and publish — eight angles, turntable, dimensions, polygon count, all visible before you buy.

Who runs this

Brethof AI is operated from Poland. The team is small — we keep it that way to ship faster and answer support emails ourselves. If you email [email protected], you're emailing the same person who designed and tested the model you have a question about.
