LEGO Part Slope Inverted 45 2 x 2 with Flat Bottom Pin Black

LEGO Part 3660 – Slope, Inverted 45 2×2 with Flat Bottom Pin (Black) is a versatile, structural LEGO piece designed for creating angled surfaces, upside-down detailing, and reinforced connections. Its 45° inverted slope shape is ideal for adding symmetry and style to the undersides of vehicles, buildings, mechs, and terrain.

The flat bottom pin allows for a stronger, more secure connection to anti-stud surfaces, making this part essential for SNOT (Studs Not on Top) techniques and reinforced structural design. The black color makes it easy to blend into builds that use darker palettes, such as LEGO Star Wars, Technic, Batman, and City vehicles.

Perfect for creating underside contours, wings, hulls, frames, and custom mechanical details, this part adds both function and style to MOCs and official sets.
