Lesson of the day: don't type a reply in a window that you left open the whole night... you will get "token expired" and have to retype everything.
Anyway, the main reason I mentioned Filip's latest images is that I believe that his sensor holder will be spring loaded and not for us to start drooling over it
Faddy's design relies on accurate distance between the PCB and the 3D printed piece, also including how deep the sensor goes into the socket.
Spring loaded sounds like a better idea and that piece should be easily printable. Not sure how Filip is dealing with the sensor alignment though...
