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
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.
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
Etsy buyers pay $12 to $26 for clean design, but Walmart marketplace sellers undercut at under $10. It needs PETG rather than PLA, real drainage and a look that holds up in a kitchen, and it does not touch food directly, though constant wet use means residue and mould in the layer lines.
