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
Check file terms, and state a load limit since the seller carries the risk if a shelf fails. Generic shelves are low risk, and sculptural ones only become a problem when copied from another maker. Etsy asks for your own original design, so a licensed file may not qualify.
