Frequently asked questions

Is the keychain generator really free?

Yes. Designing and previewing is completely free with no account. Downloading the STL just needs a free MakerNest account — no payment details, no subscription.

What size should a 3D printed keychain be?

A tag height of 25–35mm with 3–5mm thickness works well for most printers. The width adjusts automatically to fit your text.

How should I print it?

Print flat on the bed with 0.2mm layers and 2–3 perimeters. No supports needed. Pause at the text height and swap filament colour for a two-tone effect.

Can I sell prints of keychains I generate?

Yes — anything you create with MakerNest generators is yours to use, print and sell.
