Where each $6.00 sale goes
Filament, power, your time $3.81Marketplace fees $1.02Left from this sale $1.17
One sale ties up the printer for about 0.45 hours. $1.17 ÷ 0.45 h = $2.59 per print hour.
At the typical product's mid price, if it sells. Shipping not included.
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
Be aware before you sell
One Getly STL states personal and commercial use of prints is allowed, while files on other sites need a separate check. Generic clips are low risk, unless a clip uses a known character shape. 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
Plain plastic clips sell for $3.34 and free files print in minutes, so there is no price to defend. Only an animal-shaped gift set near $15 stands out, and that sells on looks rather than function.
