Not a L*GO Brick

Not a L*GO brick

It's the same dimensions as a L*GO brick (but for legal purposes it's not, OK?)

The template for the bottom is the last image.

It should fit together with other bricks, but I haven't printed it (if you do please let me know).

One of them is filleted on the top studs (Version 2) and the other is not (Version 1).
