4B EngraverKeychain tag
Rounded 50 x 25 mm keyring tag, 3 mm thick, with a 4 mm ring hole. Prints in about 15 minutes with no supports.
What fits on it
These are measured on the actual geometry, not estimates. A recessed stroke narrower than 0.8 mm closes up on a 0.4 mm nozzle, so anything below that is thickened automatically or refused.
| Size | 50 x 25 x 3 mm |
|---|---|
| Material | 3.6 cm3 of filament |
| A name on its own | up to 7.7 mm tall, 1.8 mm strokes |
| Name plus a serial | 7.8 mm tall |
| Logo face | logo up to 22.0 mm across |
| Deepest safe engraving | 2.2 mm (1.2 mm is the default) |
How to personalize it
One face carries a logo - the built-in one or a PNG/JPG you upload - with an optional serial number underneath. The other face carries exactly one of a name, a serial number or a logo. You get a live 3D preview, then a Bambu Studio 3MF (print profile and paint-on supports kept) and a plain STL. Batch mode numbers a run of them consecutively and returns one zip. No sign-up, and files are deleted after 7 days.
Printing it
Designed by 4Brains with parametric code, so it prints flat with no supports. Tested on a Bambu Lab H2S with a 0.4 mm nozzle at 0.12 mm layers in PLA on a textured PEI plate. The default 1.2 mm engraving is ten layers deep, which is also enough to fill with a second color at a filament swap - see how deep an engraving should be and the smallest text a 0.4 mm nozzle can print.
Try it on your own model. Upload an STL or 3MF, add a logo, a name or a serial number, and download a print-ready file.
