A pair of cufflinks inspired by the Piston - Rod assembly in an internal combustion engine. In fact, these cufflinks are a 1:6 scaled replica of a real Piston - Rod assembly (with a few, unnoticeable modifications to comply with the 3D printing rules).
The great thing about these is that they won't look cheesy on the outside, as they will appear to be plain cylinders with some rings removed.
The Polished Surface Finish adds a lot more realism, as the surfaces that are unreachable for polishing make it look as if it had just come out of casting/forging, while the rest has a mirror finish as if machined. Just the way it looks in a real life piston.
Discrete and low profile, yet classy. Ideal for fashionable mechanical engineers.
