Why it can work

- Seasonal demand: Christmas and housewarming gifting
Why it might fail
- Crowded market, so prices can fall fast
- Under $2 estimated profit per print hour
Be aware before you sell
Parametric generators on MakerWorld have their own terms, so check commercial rights before selling output. Geometric sets are low risk, while themed sets using logos or film imagery are not. Etsy asks for your own original design, so a licensed file may not qualify.
How to get a file you may sell
- Make your own. Tinkercad is free and enough for simple shapes.
- Buy a commercial licence. Many designers on Cults3D, MyMiniFactory and Etsy sell one. Read what it allows.
- Use open licences. CC0 and CC BY allow selling prints. NC does not. Filter by licence on Printables or MakerWorld and keep a screenshot.

Our take
Sets sell at about $12 or less (low end is CA$11.69 converted at an assumed 0.72), so little remains after shipping once free delivery is matched. It only works as a personalised gift, and fails on hot mugs softening PLA or on price against generic sets.
