The first print is a proof, not a product. It tells you whether the theme reads, whether the small parts survived, and whether you want five more.
Look at the face first
On a Duck Heroes duck the eye is the signature: long, narrow, and vertical, like a capsule. If the eyes are blobby, closed, or full of strings, the character is gone even if the hat is perfect. Pause and fix orientation, cooling, or layer height before you start a batch.
The bill is the other fragile read. A bill full of supports can look chewed. If the designer’s note, when you have one, suggests an orientation, follow it. General setup is in how to print small ducks.
Check the costume at arm’s length
Hold the duck at the distance it will sit on a shelf. You should get the theme without a caption. If you cannot, more paint will not save a muddy silhouette. Collectors buy the read. See themes.
Measure it
Write down height, width, and weight. Your listing and your postage both need those numbers. A slicer estimate is a start. A scale is the number you ship.
Decide on color after the shape works
A first print in a plain filament shows defects. A five-color hero print hides them until you have already spent the time. Get one clean body, then move to color or multicolor.
Only then think about a listing
If you plan to sell, confirm the license covers physical sales. Photograph this print, not an earlier render. One honest photo of a first article is more useful than a grid of ducks you cannot reprint the same way.
Duck Heroes files are not available for download on this site yet. When they are, the same first-print habit still applies. A new theme earns a place in the row only after you have held it.
