IMPORTANT: Print the bricks with line width set to 0.45. You may need to adjust flow before the bricks stay together well. If the bricks are too loose - add 1%, if they're too tight - reduce by 1%.

The spikes can be very sharp. Don't actually use them to harm anyone.

There are 11 different versions of the brick: 1x1, 1x2, 1x3, 1x4, 1x6, 1x8, 2x2, 2x3, 2x4, 2x6, 2x8. If you need a different size feel free to leave a comment, I will add it asap. 

The spikes are designed to fit under the brick above, so that they can be stacked on top of each other. 

Included are also GCode files for Prusa MK4/MK3S/MINI printers. One file prints every single brick, and the other prints 6 x regular 2x4 brick, which can be assembled in over 900 million different ways.
