Turn STL uploads into recurring royalty income when sellers fulfill physical orders, not just one-time downloads.
Selling STL files as digital downloads caps revenue at the file price and attracts pirates. Printlooper lets designers upload STL or 3MF assets, set royalty terms, and earn whenever sellers move physical units through the supplier network. You create; sellers merchandise; suppliers print. Stripe Connect pays you on your plan schedule.
Upload once, earn on every fulfilled unit
Publish validated STLs to the marketplace with royalty percentages aligned to your subscription tier. Each time a seller converts a order, your royalty settles before margin splits downstream.
Higher designer subscription tiers increase base royalty rates and payout speed for designs that sell at scale across multiple storefronts.
Automated validation protects your reputation
Mesh validation catches non-manifold geometry and common printability issues before sellers list your work. Fewer failed jobs mean better customer experiences and more repeat royalties.
Document orientation and material notes in listing metadata so suppliers succeed on the first print.
Reach buyers who never print at home
Sellers acquire customers who want finished parts shipped, an audience digital STL stores never capture. Your design earns on every box that leaves a supplier dock.
Multiple sellers can list the same STL, multiplying discovery without multiplying your upload effort.
