Benda LFC700 | Fine Line Motorcycle Keychain

A small motorcycle silhouette reduced to a connected network of lines and open spaces. The design suggests the long wheelbase, low seat pocket and low exhaust line. This interpretation uses the standard model reference generation; it is an abstract illustration, not an exact scale replica. Other generations can look different.

The keyring eyelet follows the tail line. The wheels, engine details and frame are connected to the same flat body.


- Approx. 74.4 × 33.3 × 3.0 mm at 100% scale.
- Nominal keyring opening: 4.6 mm. Check your split ring against the opening and 3 mm part thickness.
- Main strokes: 1.4 mm; fine wheel / brake-disc strokes: 1.2 mm; outer wheel rings: 1.8 mm before polygon approximation.
- STL: one part in millimetres.
- 3MF: the same model geometry in millimetres, with no printer, filament or slicing profile.


Print flat, with the broad face on the bed. Starting point: 0.4 mm nozzle, 0.20 mm layers, two to three walls where the geometry allows, and 100% infill for this small part. The thin strokes may fit fewer paths than the requested wall count; inspect that every stroke has continuous, filled toolpaths. The flat geometry is designed to avoid support material. PETG is a candidate for a daily-use keychain. PLA can be used for a first prototype. Tune adhesion and first-layer expansion for your machine.

Do not reduce below 100% without checking every thin line and opening in the slicer. Remove sharp first-layer edges after printing if needed. Check the eyelet and all connections before use.
