As of my last update in 2023, there is no specific LEGO set numbered 2780. However, you might be referring to a commonly known LEGO element or part, rather than a set. Part number 2780 is a black Technic pin, also known as a “Technic Pin with Friction and Slots.” This piece is a fundamental component in the LEGO Technic system and is widely used to connect Technic beams, gears, and other elements securely without the need for snapping together like traditional LEGO bricks. The friction ridges allow for a tight fit, ensuring that Technic models are sturdy and functional. This piece is incredibly versatile and appears in countless LEGO Technic sets, contributing to the construction of vehicles, machines, and robotic models among others, showing the depth of LEGOs commitment to inspiring mechanical and engineering creativity in builders of all ages.
