HELICOPTER BRICK

THIS IS A SIMPLE HELICOPTER MADE OF BRICKS, IF YOU HAVE YOUR MACHINE WELL CALIBRATED, THE PIECES WILL FIT WELL, BUT IF NOT, YOU WILL NEED TO PLAY WITH THE HORIZONTAL EXPANSION SO THAT THE PIECES JOIN CORRECTLY, YOU ALSO HAVE TO HAVE GOOD ADHESION TO THE BED, SINCE THEY ARE SMALL PIECES THAT CAN DEFORM AND COME OUT OF IT, YOU CAN SCALE THEM HOWEVER YOU WANT <3
