How it works

Simple for you.
Traceable for every download.

Three steps, set up once, runs automatically for every patron.

01

Upload your original file

Connect your Patreon and upload your model. STLTracer stores the original securely and it's never delivered directly to anyone.

02

Each patron gets their own copy

When a patron clicks your link and authenticates with Patreon, they receive a uniquely tagged version, different from every other patron's copy.

03

Investigate a leak in seconds

Found a file circulating online? Upload it to STLTracer. The system cross-references it against your download records and identifies who leaked the file.

Why STLTracer

Built for creators
who take their work seriously.

Everything in the background. Your patrons never know it's there.

Invisible to patrons

The files look and print exactly as expected. No visible markings, no change in quality, no extra steps for your audience.

Every format supported

STL, 3MF, or ZIP bundles with multiple files, all traced individually and automatically, with no manual work needed.

Patreon-native

Connect your Patreon once. Access control by tier, automatic delivery, no extra login for your patrons.

Full download history

Every download logged with name, email, and Patreon ID. A clear record to support any action you decide to take.

Update your original file, links stay the same

Release a new version without changing the download link. Patrons automatically get the updated file next time they download.

Suspicious activity alerts

You get an email if a patron downloads the same model an unusual number of times, so you can act before a leak spreads.

Questions

Honest answers
to common questions.

Is this DRM? Will files still print normally?

No. STLTracer is not DRM. Files print exactly the same, same quality, same format, no quality loss. The watermark is invisible to the eye and to the printer. Your patrons see and print files identical to what you upload.

Do my patrons need to install anything?

Nothing. Your patrons log in with Patreon (same account they already use), click the link in your post, download. No new app, no new password, no plugin. Zero friction added.

What happens if I cancel?

Cancel anytime, no fees, no questions. Your account downgrades to the Free plan at the end of the billing cycle. Your existing files stay accessible, you keep the leak-detection history. If you re-subscribe later, everything is right where you left it.

How fast can I identify a leaker?

Upload the leaked file, result in under 30 seconds. The system matches the watermark against your patron database and returns the exact name + email + download date of the patron who shared it.

BUILT BY

Bruno Revoredo · brazilian founder based in the UK

Software engineer · 3D miniature painter on the side

I started STLTracer after a designer friend lost around $300/mo Patreon revenue to one specific leaker she could never identify. Patreon support: "nothing we can do." That was the kick.
