Where each $8.50 sale goes
Filament, power, your time $4.07Marketplace fees $1.07Left from this sale $1.37

At the mid price, if it sells. Shipping not included.
Why it can work
- Seasonal demand: Christmas stocking fillers
Why it might fail
- Under $2 estimated profit per print hour
- Blind packs mix many files, so one unlicensed design can trigger a claim on the listing
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Every design in the pool needs its own commercial right, and Etsy's original-design rule applies to each one. Blind packs mix many files, so one unlicensed design can trigger a claim on the listing. 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
Random selection lets a seller use up leftovers and spares, which helps a low price of about $4 to $7. It works as a cheap add-on to a main order, and fails as a stand-alone product once shipping is added.
