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, birthdays
Why it might fail
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Confirm commercial rights per file, as with the Thangs labyrinth gift box, and check Etsy's original-design rule. Puzzle mechanisms can come from named designers, so copying a known box is the main risk, though no takedown was found. 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 printed box can undercut wooden ones at $36 and up while staying a real gift. It works with a clever own mechanism and gift-card positioning, and fails if the fit is loose, since the puzzle is the whole product.
