Print it instead of buying it.

Print The Cart is a free browser add-on. When you search on Amazon, it shows proven 3D-printable versions of what you're shopping for, with what it costs to print at home.

Coming soon to Firefox Chrome will follow.

How it works

Search like normal

Shop on Amazon the way you already do. Nothing extra to open.

See what you could print

When a strong printable match exists, up to two cards appear first, with the cost of filament and power.

Get the files

Open the model on MakerWorld, download it, and print it. The maker keeps full credit.

Only good matches

Every model in the library, over 9,000 of them, was reviewed as a real substitute for something people buy. If there is no strong match for your search, Print The Cart shows nothing. Matching runs inside your browser, so your searches are not sent to us.

Support the project

The add-on and its model library are free. Keeping the library current costs real server time, so supporters get a fresher, larger version.

$12 for 12 months

Support opens inside the add-on once it launches.
