Which models you may sell prints of
The license that a designer chose for a model decides whether you may sell what you print from it. Prusa says 3D models are generally free to download under Creative Commons Attribution-NonCommercial, which means they are not to be used commercially. Selling a print counts: the license deed defines a commercial use as one primarily intended for commercial advantage or monetary compensation.
Three Creative Commons licenses allow selling. CC BY and CC BY-SA let you use a model “for any purpose, even commercially”, as long as you credit the designer. CC BY-SA adds that a remix you share must keep the same license. CC0 allows commercial use without asking permission and asks for no credit.
Licenses you can buy
In December 2023, Prusa named three licenses that a paid model in the Printables Store can carry. The Standard Digital File license allows personal use of the model and its prints. The Commercial use license allows selling prints, modified versions included, and the Commercial use no derivative license allows selling prints of the model as it is.
On MakerWorld, Bambu Lab added a Commercial License Membership in February 2025. Each creator sets its price, from $3 to $300 a month, and Bambu Lab calls commercial licensing essential for people who sell physical prints of models on MakerWorld.
What a sale costs you
On Etsy in the United States, a listing costs $0.20 whether or not it sells. A sale then pays a 6.5% transaction fee on the order total and 3% plus $0.25 for payment processing. Together that is 9.5% and $0.45 for a listing that sells once.
Etsy also has rules of its own about 3D printed items in its Creativity Standards, so read them before you list. The 3D print pricing calculator takes the fees and sets a price that leaves your markup intact after them. Weigh your spools with the spool weight page to know how much filament is left for the orders.
