Short answer: only if the model's licence allows it. Being free to download doesn't make a model free to sell. Here's how to tell.
This guide is general information, not legal advice.
Every model has a licence
On Printables, Thingiverse, MakerWorld, and similar sites, the designer chooses a licence for each model. It's shown on the model's page, and it's the licence that decides what you can do, not the site.
Creative Commons licences, decoded
Many models use a Creative Commons (CC) licence. The letters tell you the rules:
| Letters | Meaning | Can you sell prints? |
|---|---|---|
| BY | Credit the designer | Yes, with credit (unless NC is also present) |
| SA | Share-alike: changes must use the same licence | Yes, unless NC is also present |
| ND | No derivatives: don't change the model | Depends on the rest of the licence |
| NC | Non-commercial | No |
| CC0 | Public domain | Yes |
The rule of thumb: if "NC" appears anywhere in the licence, you can't sell prints. CC BY-NC, CC BY-NC-SA, and CC BY-NC-ND all forbid commercial use.
Some sites also have their own licences, such as "personal use only" or "standard" licences. Read what each one allows.
Commercial licences
Many designers sell a commercial licence separately, often as a monthly membership (for example on Patreon, MyMiniFactory, Cults3D, or MakerWorld). These let you sell prints, usually with conditions such as a sales limit, a requirement to credit the designer, or ending when your membership ends. Keep a copy of the terms.
Watch out for characters and brands
A licence can only give rights the uploader actually has. A model of a famous character, logo, or brand uploaded by a fan doesn't give you permission to sell it, whatever licence is shown. Those rights belong to the company that owns the character or brand.
Protect yourself
- Screenshot the licence and the model page, with the date, before you start selling.
- Keep commercial licence receipts and membership records.
- Credit the designer where the licence requires it.
- Stop selling if the licence changes or a designer asks you to, and ask for advice if you're unsure.
What about printing a customer's file?
If a customer sends you a file to print for them, they should have the right to have it printed. On the Nozzlet directory, customers confirm they have those rights before uploading, and each shop can choose whether to accept files licensed for non-commercial use. Whether paid printing of an "NC" file for someone's personal use counts as commercial use isn't settled, so decide your own policy and apply it consistently.
A note on Etsy
Since mid-2025, Etsy's creativity standards only allow 3D-printed items made from the seller's own original designs, even if you've bought a commercial licence for someone else's design. See Selling 3D prints on Etsy.
