Filament, power, your time $7.32Marketplace fees $1.78Left from this sale $4.90

Why it can work
- Low brand or licence risk if the design is your own
Why it might fail
- Under $2 estimated profit per print hour
Be aware before you sell
Free Printables dispensers exist, but their licences were not verified, and one combined model is sold at $5. Generic storage carries little brand risk, unless a design copies a specific seller's dispenser. 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
A gravity-fed dispenser at about $25 looks like the only version with margin, because plain boxes drop to about $4. It needs a distinct mechanism and clean tolerances, since jamming would ruin reviews.
