This is a internal mount for an ArduSimple Survey GPS antenna mount for the Yardforce Classic 500 - the main mower of the OpenMower project (https://github.com/ClemensElflein/OpenMower).

My chassi is six month older as the one from this guy (https://www.printables.com/model/477732-openmower-survey-gps-antenna-mount) and has not the required mountings - so I designed my own.

Should the Multi- and Triband survey antenna.

The antenna connection is so tight that I screwed the antenna first on with the cable connected and could not screw the mount to the case.
The following angle adapter has enough clearance to even unscrew it:

Print instructions:

• I've printed this in ABS and to be on the save side you should probably go for ABS or PETG since it might get hot inside the mower during summer - If somebody used PLA report back if it holds up.
  
• I also recommend to set a modifier in your preferred slicer to adjust the walls to 5 and set the infill a bit higher on the thread an 1mm down into the mount base.
  
• It is also designed to fit a max 10mm M3 washer with a M3x25 screw to secure the thread from snapping off.
