3D PRINTABLE DIGITAL DOWNLOAD - This unit replaces your factory suction cup mount holder. I created this model after my factory clip-in-mount was run over and broken. Simply unscrew your old clip-in-mount and screw this mount to the suction cup component(can be purchased with RAM suction mount if you order printed version). Stratus fits very snug. If your using your Stratus as a backup AHARS, then you want the unit secure so that the calibration holds and does not drift. Can be removed and replaced very quickly. I actually used photogrammetry to capture a 3D model of the Stratus and then built my model around it.
