About this 3D model
I made a small mount, with snap-on lid, for the Crius CN-06 module. The mount is made to fit on top of the PX4FMU, but could be used onto any flat surface (where the snap-on can pass over the edge). On the image, a 3DR-radio is fit between the PX4FMU and the Crius mount as well, but there are no mounting holes/fixtures for this.
