A license page is easy to skim and easy to misread. Use this checklist on any designer’s terms, including the Duck Heroes commercial license, before you print a box of stock.
1. Confirm you have the selling right
Personal use and commercial use are different grants. A download, a tip jar, or a “credit the designer” note is not a commercial license. Look for words that say you may sell physical prints.
If the catalog is not open, do not treat a blog post as permission. Permission is the license attached to the file you actually receive.
2. Check the clock
Some licenses last forever for that file. Some last only while you keep a membership. Duck Heroes selling rights exist only while the commercial license is active. After it ends you get 30 days to sell physical pieces you already printed. You do not get 30 days to keep printing new ones.
3. List your sales channels
Write down where you actually sell: Etsy, your own site, a weekend market, a comic convention, a local shop. Then read the channel list. Duck Heroes allows ordinary retail and online shops worldwide. It does not allow you to hand the digital file to customers as a bonus.
4. Look at manufacturing
Hiring a print farm is allowed if the farm only fills your orders, gains no right to sell the design, and deletes the file when the job is done. Injection molding, casting, and die-casting are not covered.
5. Read the file rules twice
This is the clause people skip.
- No uploading to model sites
- No sharing in a Discord or a group chat
- No reselling the STL
- No publishing a remix, even if you changed the hat
Color changes, paint, and a keyring are physical changes. They do not create a new file you can distribute.
6. Protect the brand, and other people’s brands
Do not name your shop after the designer. Do not use their logo as your avatar. And do not describe a character duck as an official product of the studio that owns the character. Say what is true: it is a 3D-printed duck inspired by a theme, designed by the maker named in your license.
7. Save a copy
Keep the version date of the license you relied on, next to the order or membership record. If a question comes up later, you want the text you agreed to, not a memory of it.
If you want the short version of the Duck Heroes rules, the license summary is written in plain sentences on purpose.
