Where each $18.00 sale goes
Filament, power, your time $5.34Marketplace fees $1.97Left from this sale $8.69
One sale ties up the printer for about 3 hours. $8.69 ÷ 3 h = $2.90 per print hour.
At the mid price, if it sells. Shipping not included.
Why it can work
- Low brand or licence risk if the design is your own
- Seasonal demand: Christmas and Father's Day, my estimate
Why it might fail
- No major warning found, test small first
Be aware before you sell
Paid and free jig files differ, and some Thangs files sit behind a membership, so check selling rights. Mostly functional, but do not clone patented commercial jig mechanisms or use Festool and similar names beyond fit. 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
Woodworkers value tools and pay for accuracy, but many also own printers. It works when the jig pairs with a steel bushing and a popular YouTube project, and fails if bare plastic wears out or loses accuracy.
