# Printwright Personal Print License — v3 **This is a template license, not legal advice.** Printwright provides this text as a standard grant between a designer and a buyer; neither Printwright nor the designer has tailored it to your situation, and you should consult a lawyer for anything that matters more than a shelf bracket. ## 1. Parties and subject This license is granted by the **designer** (identified by the stable `designer` id in the license certificate — an identity, never a wallet) to the **licensee** (the holder of the license certificate identified by `cert_id`), for the 3D model whose file bundle hash is recorded as `model_hash` in that certificate. ## 2. Grant The designer grants the licensee a perpetual, non-exclusive, non-transferable license to: - download and keep the model's file bundle; - print the model, and modified copies of it, on their own or third-party printers, in unlimited quantity, **for personal, non-commercial use**; - make personal-use modifications of the files. ## 3. Not granted The licensee may not: - sell, rent, or otherwise commercially exploit printed copies of the model; - redistribute, resell, sublicense, or publicly share the digital files, modified or not; - present the model or a derivative as their own original design. A separate Commercial Per-Unit license covers selling printed copies. ## 4. Designer's warranty The designer warrants that they hold the rights needed to grant this license and that the model is their own work or work they are licensed to sell. The designer — not Printwright — is responsible for this warranty, and accepted it when publishing the model. ## 5. No DRM — the honesty clause The files carry no copy protection, watermarking, or usage tracking, and none will be added later. This license works on honesty: the price of a license is set low enough to pay. If you share the files anyway, no mechanism stops you — you are simply breaking a promise this document records you made. ## 6. The certificate Each purchase anchors a certificate to the Hedera Consensus Service as an **opaque commitment** — a salted hash of the certificate, and nothing else. The personal certificate records the model hash, license type, payment transaction, and a hash of this exact text (`terms_hash`), but no sequential sale or unit number. The certificate is held off-chain and revealed by you: anyone you show it to can recompute the hash and verify it against the public mirror node without trusting Printwright. Because only the commitment is public, no buyer, designer wallet, or per-model sales count is broadcast. The certificate is the durable proof of this grant; keep your `cert_id`. ## 7. Termination This license ends automatically if the licensee breaches section 3 and does not cure the breach within 14 days of notice. Printed personal copies made before termination may be kept. ## 8. Liability The model is provided **as printed-tested by the designer, but otherwise as-is**. To the maximum extent permitted by law, neither the designer nor Printwright is liable for damages arising from printing or using the model. Total liability is capped at the price paid for this license. ## 9. Governing law *Placeholder:* the governing law and venue are those stated on the marketplace's terms-of-service page at the time of purchase, unless designer and licensee agree otherwise in writing.
