  We present a 3D mapping of the Wolf-Rayet (WR) nebula M1-67 around WR124. We
obtained high-resolution San Pedro M\'{a}rtir (SPM) Manchester Echelle
Spectrograph (MES) observations along 17 long-slit positions covering all
morphological features in M1-67. We are able to unveil the true morphology of
M1-67 and its kinematics by interpreting the SPM MES observations by means of
the 3D modelling tool for Astrophysics SHAPE. Our SHAPE model that best
reproduces the SPM MES data includes three concentric bipolar structures
composed by a hollow ellipsoidal structure and a torus. In addition, the model
requires the presence of expanding jets and broken blisters in order to
reproduce specific spectral features. Our results are consistent with the idea
that M1-67 and its progenitor star WR124 have formed through a common envelope
scenario that occurred 11.8$^{+4.6}_{-0.8}$ kyr ago. Our bipolar model strongly
questions previous suggestions of the presence of a bow shock structure
surrounding M1-67. We interpret that the bright structures detected in the
spectra extracted from the central regions are produced by wind compression at
the receding region of the innermost structure in M1-67. Furthermore, WR124 is
moving through a low-density region above the Galactic plane that has
negligibly affected the formation history of M1-67.
