BME 280 sensor mount bottom part remix

This is a redisign of an existing BM280 sensor box tha i modified to suit better my needs.
It has a small hole to accomodate a magnet for fixation to metalic objects and the hole for the screw to fix the sensor is in a different position from the original design as my sensors are a bit biigger (they have 6 instead of 4 holes for wiring).
