4B EngraverUSB-C cable winder
Pocket winder for the 2 m MacBook USB-C charge cable: a 66 x 42 x 34 mm body with a 24 mm deep groove that takes the whole cable in two layers, plus a slot to park the plug. Both faces are flat - logo one side, name or serial the other.
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 | 66 x 42 x 34 mm |
|---|---|
| Material | 61.3 cm3 of filament |
| A name on its own | up to 10.2 mm tall, 2.39 mm strokes (set sideways to use the longest clear strip) |
| Name plus a serial | 10.2 mm tall |
| Logo face | logo up to 22.0 mm across |
| Deepest safe engraving | 33.2 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.
