Why it can work
- Limited positive evidence so far
Why it might fail
- Crowded market, so prices can fall fast
- Under $2 estimated profit per print hour
- Cute character sponge holders get copied widely on marketplaces, so a seller should use an original design and not clone a popular one
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Free sink caddy files exist on Printables and MakerWorld, but commercial terms were not checked. Cute character sponge holders get copied widely on marketplaces, so a seller should use an original design and not clone a popular one. Etsy asks for your own original design, so a licensed file may not qualify.
