My objective is to use less parts as possible, easy to print and easy to assemble.The JST connector on the opto coupler was removed and wires are soldered directly to the board. ABS or PETG recommended for printed parts
Servo used : Hitec HS-40

Mounting hole distance : 19 mm center to center
Others : 4 10mm m3 screw, 2 to secure the whole assembly and 2 to mount, the probe tip is a 3/4 inch brass picture hanging nail, it has a nice rounded head that works great for the purpose it also provides the weight to drop the flag when the probe is deployed without the use of a spring. For the arm, I used one of the provided servo horn, cut it and shaped it accordingly.
