ZOHD Altus - Hatck lock

Since I decided to use the GPS Magnetometer on my ZOHD Altus, I had to remove the magnet of the battery hatch. In order the keep the original hatch I created a lock that do not need a lot of change on the plane and hatch.

The ring go right in the hatch hole and need to be glue in place, but be carrefull to put it in the right orientation (with the lock oriented front).

The handle is screwed on the lock with two M2.5x6 screw.

You need to cut a hole right under the GPS location 10mm under the middle, it need to be 3-4mm high, 25mm width decenterd on the left (use the cutting model) and 8mm deep.
