About the 3D Keychain Designer
Design a personalized 3D-printed keychain in your browser: no account, no CAD software. Pick from 5 shape presets (rounded rectangle, circle, hex, heart, star), type a name or message with raised or carved text per line, drop any of 17 symbols right into the text, tune the base thickness and relief height, and optionally include a small charm disc with its own symbol. Export a binary STL ready for Bambu Studio, Cura, PrusaSlicer, OrcaSlicer, or any FDM slicer.
Frequently Asked Questions
What does the STL contain?
A solid keychain blank in your chosen shape, with the keyring hole punched through, plus your text and any inline symbols rendered in real 3D geometry. If a charm is enabled, a small disc with its own symbol is also included, packed beside the main tag.
Is the text really part of the STL?
Yes. Every line of text is extruded into the STL, either raised on top of the base or carved down into it (you choose per line). Symbols inserted inline with the text (hearts, stars, and 15 more) are extruded the same way, so what you see in the preview is exactly what prints.
What relief height should I pick?
0.6–1.0 mm is a good range for raised symbols. Below 0.4 mm the relief is hard to feel; above 1.5 mm the symbol may need extra perimeters or sturdy infill. Match relief height to a multiple of your layer height for the cleanest top finish.
Do I need to create an account?
No. Everything runs in your browser, completely free. No sign-up, no account, and no uploads. Designer Bee keeps only anonymous usage stats, like which settings get exported, to keep improving the tools.
