COMMERCIAL MEMBERSHIP

Remove the back engraving

Without a verified membership, your STL and 3MF downloads include back engraving.

About Trio & the Creator

Jackson’s 3D World

Explore more 3D printing projects, designs, and updates from the creator of Trio.

Create batches from typed names or Google Sheets. Review each keychain, then choose an STL ZIP, an individual 3MF ZIP, or one 3MF project with separate plates. Google rows are marked Designed after your download is prepared. Skipped names stay undesigned.

JACKSON’S 3D WORLD

Verify your commercial membership

Verify your MakerWorld account, then Trio checks for an active Jackson’s 3D World commercial membership. Verified members can turn back engraving on or off in Settings.

Don’t have a membership? Join on MakerWorld

Use the email you use to sign into MakerWorld/Bambu. The sign-in code comes from Bambu Lab/MakerWorld.

After verification, open Settings and uncheck Include back engraving to remove it from your batch. Personal-use downloads keep the engraving.

How verification works

Trio sends your email and code to Bambu/MakerWorld, verifies your account identity, then checks the synced commercial member list. Your MakerWorld password is never requested. Trio keeps your verified profile identity, not your MakerWorld access token.

Membership is checked again before downloads and every five minutes while this site is open. If verification fails, back engraving stays included.

Have an access code from Jackson’s 3D World?

An access code links your verified account. Your commercial membership must still be active.

Have a temporary watermark code?

Enter a code from Jackson's 3D World to remove the back engraving until it expires. You can still verify your commercial membership by signing in above.
