LEGO Part Slope, Inverted 33 3 x 2 with Flat Bottom Pin and Connections between Studs

LEGO Part 3747b – Slope, Inverted 33 3×2 with Flat Bottom Pin and Connections Between Studs is a versatile inverted slope element designed to create smooth, angled surfaces on the underside of builds. With a 33° angle and a 3×2 stud footprint, this part includes a flat-bottom anti-stud pin and internal supports that allow for stronger, more stable connections, especially in SNOT (Studs Not on Top) techniques.

Builders often use this inverted slope to form vehicle undercarriages, spaceship hulls, architectural arches, support structures, and aesthetic reversals for symmetry in MOCs. The extra bottom pin provides a better grip and reinforcement, making it a popular choice for LEGO Technic, LEGO Star Wars, LEGO City, and LEGO Creator Expert builds.

Whether you’re creating smooth transitions, inverted wings, angled armor, or filling gaps with style, this slope adds both functionality and clean visual detail.
