It is becoming increasingly clear that the main agents must operate at their innermost regions, where a significant equatorial density enhancement should be present and related to the collimation of light and jet launching from the central star preferentially towards the polar directions. Most of the material in this equatorial condensation must be lost during the asymptotic giant branch as stellar wind and later released from the surface of dust grains to the gas phase in molecular form. Accurately tracing the molecule-rich regions of these objects can give valuable insight into the ejection mechanisms themselves. We investigate the physical conditions, structure and velocity field of the dense molecular region of the planetary nebula NGC 6302 by means of ALMA band 7 interferometric maps. The high spatial resolution of the 12CO and 13CO J=3-2 ALMA data allows for an analysis of the geometry of the ejecta in unprecedented detail. We built a spatio-kinematical model of the molecular region with the software SHAPE and performed detailed non-LTE calculations of excitation and radiative transfer with the shapemol plug-in. Description: SHAPE model of the 12CO and 13CO J=3-2 emission of the planetary nebula NGC 6302, to be matched to ALMA observations as described in the paper. The file is intended to be loaded with SHAPE v5 (http://www.astrosen.unam.mx/shape/) and makes use of the SHAPEMOL plugin to achieve the radiative transfer in CO species (i.e. The CO data tables in http://www.astrosen.unam.mx/shape/v5/Downloads/SHAPE_INSTALLERS/index. html must be downloaded and pointed at within SHAPE). For additional details on how to work with SHAPE+SHAPEMOL, see Santander-Garcia et al. (2015, Cat. J/A+A/573/A56).
