How the score adds up
Demand and legal risk come from the niche Articulated sharks. An idea to test can score 69 at most until someone has seen it for sale.
Why it can work
- Low brand or licence risk if the design is your own
Why it might fail
- Crowded market, so prices can fall fast
- Under $2 estimated profit per print hour
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Most files seen are paid downloads with terms not checked, so confirm commercial rights per file and check Etsy's original-design rule. Real animals carry little trademark risk, though each file stays its designer's copyright. Etsy asks for your own original design, so a licensed file may not qualify.
