Why Portals

Zero startup cost

Portals is completely free. No subscriptions, no listing fees, no minimums. You only pay production out of each sale.

Live in under a minute

Upload an STL, get an instant quote, set your price. Your product is live and shareable immediately.

Infinite scale on day one

Thousands of printers behind every listing. If your product goes viral tonight, it ships tomorrow.

We handle everything

Printing, packing, shipping, payments, taxes, returns, customer support. You just design and promote.

Bundle real hardware

Add screws, magnets, wireless chargers, and other components to your prints straight from our parts catalog.

Your brand, your storefront

Customize colors and layout, generate QR codes, and share a link that feels like your own shop — not a marketplace listing.
