slicing ASX1_SWX1_raspi_cam_bracket

[lagoa01]

Hi. I am trying to slice this stl file. I tried Cura and it gave me an appropriate slicing but i would want to have a comparable slicing with S3D.
In fact, i've tried different parameters but S3D slice by separating parts see image in attachment . Anyone know how to parametrize correctly S3D
Thanks in advance[/img]
