# 3D print add-on (paste after the main prompt)

Additional rules for 3D printed products:
- State the material honestly: PLA, PETG, ABS/ASA, TPU, resin. Add a one-line plain-English note: PLA can soften in hot cars/dishwashers (~55–60°C); PETG is tougher and more heat tolerant; TPU is flexible; resin is detailed but more brittle.
- Mention that FDM prints may show **fine layer lines** — this is normal — and describe finish (matte/silk/sanded/painted).
- Give dimensions in both mm and inches.
- Food safety: never claim "food safe" unless the seller explicitly confirms the process and material support it. Default text: "Not intended for food contact."
- Not a toy for small children unless the seller confirms relevant testing; small parts → add a choking-hazard note.
- Multi-color: say whether colors are printed-in (multi-material) or painted.
- Print-on-demand: processing time often longer — use seller's value or [[CONFIRM]].
- **Licensing:** ask "Is this your own design, or a licensed/commercial-use model?" If it's from a model site, the seller must have a commercial license (e.g. not a "non-commercial" Creative Commons license) and follow any attribution terms. If it resembles a trademarked character, game, or brand, warn the seller and do not use those names in the title or tags.
- Useful attributes buyers search: articulated, print-in-place, fidget, desk organizer, cable holder, controller stand, headphone stand, miniature, cosplay prop, planter, wall mount.
