Brick (34 parts)

A LEGO brick is a rectangular prism with one or more round 'studs' on the top.

The bottom of a LEGO brick features an opening, or 'antistud' which is ever-so-slightly smaller than a stud, causing them to stick together when connected with a small amount of force.

A 1×1 brick has proportions of 5 units wide and 6 units tall. It is 8mm wide (per stud) and 9.6mm tall (excluding the height of the stud).
