Lego brick generator tool - for simple 2x1 or 4x1 bricks with brick pattern side. Very useful for architectural builds, castle walls etc.

The pattern is on both sides and it is reccesed into the brick wall so it can be stacked side by side with other bricks as genuine Lego. The actual profile of bricks “crease” is just simple “V” shape, the genuine is more complicated. However the pattern repetition is actually correct. 

Three pregenerated bricks STL files are ready for download. The 2x1 is actually “correct” brick (98283):

The 4x1 is just exactly double that however it does not currently exists in Lego system, as well as the 1x1 corner piece.

Printed bricks on photos are from Creality Ender 3 S1 with 0,2mm extruder and layer height 0,12mm
