This is a mounting base to allow an MSC10 Garmin Satellite antenna to mount where a prior Garmin GPS24XD was located. The three holes are similarly spaced, but this allows adjustment if the hole orientation on the boat isn't appropriate for aligning the MSC10. The lower portion has adjustability for the prior holes and then the top portion seats into it after it's attached to your MSC10.
Three circumferential holes will accept sheet metal screws or can be tapped for 8-32 bolts (preferred) to lock the assembly in place.
Ideally this should be printed with a UV resistant material. ASA is preferred. I'd suggest white for best reflection of sun energy and longevity. Polycarbonate and PETG are passable but may not have the same longevity. If you experience warping during ASA printing, apply a 15-20mm brim.
