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.
