OpenMower survey GPS antenna mount

This is an internal mount for the ardusimple survey GPS antenna for the open mower project. Fits in a YardForce classic 500 mower.

• Saw off a 5/8" UNC screw for antenna
• Use M4 screws for mounting.
• antenna_distance = 0,32

I added a thin EPDM rubber washer around the screw (see picture). I recommend to cut a M4 thread in the existing pins in the mower case.

• PLA, or better PETG
• Nozzle diameter 0,4
• Layer height 0,2
• Infill 20%
