Despite technically being new, the design of this anchoring brick closely mirrored the modified 2x4 Knud had come up with for the original LEGO wheel. Once again, holes were passed through each of a 2x4 brick’s walls. However, this time, instead of one hole per side, a bisecting tunnel was cast in between each pair of studs on all four walls; three on the long sides and one on the short faces.

The first Technic Brick from 1970 was based on a 2x4 brick, with holes on all three sides. (Part 3709)
