Part 3001

Part 3001, the 2 X 4 Stud part is one of the most basic of all bricks. It is most commonly used in models and is the logo of many websites and once LEGO's logo. It used to be hollow inside with slots in its sides to allow for windows and doors. After that the slots vanished and the hollow brick appeared. Followed by the biggest LEGO invention, the tubes on the bottom of the brick. This made the brick more versatile than ever before. By this time, the LEGO logo is printed on each of the studs. This brick has been seen in many colours, but most commonly red and white. Older sets had red, white, black, blue, yellow and transparent bricks in them.
The 3001 is also the brick used for most tests.
These bricks are known as Bayer test bricks and were made for LEGO by the Bayer company to test the new plastic (ABS). Other companies have been known to make test bricks too. Test 3001 come in a wide range of colours.
