Bought a Raymarine ST70 autopilot control head, and it was previously flush mounted, so it didn't come with this surface mount. I figured I could easily find one, but when that wasn't the case, I made this.

I had a pdf of the manual, and I  realized the mounting pattern in that manual was still vector in the .pdf. It was easy to bring it into a graphics program, remove the lines needed, and import that into a cad file, add thickness and depth. It was perfect!

I wonder if it will work with ST60 or other models.

Figured I'd share in case there was someone else out there needed it.
