LACK BME280 sensor mount for Ender 3

This is another sensor mount for my Ender 3. See here for my previous one:

I made another one, because i was not satisfied with the laginess of the AM2302/DHT22 on the RaspberryPi.

This mount encloses a BME280 which is supposed to be very accurate in measuring temperature, humidity and air pressure. And it is :)
Please note that the BME280 is shipped with various PCB form factors. For my mount is use a 4 pin version with a small PCB board.

For my LACK enclosure project with a temperature controled fan I needed to mount the temperature sensor near the printing area of my Ender 3 to receive as accurate temperature values as possible, which are not influenced by obstructions or drafts

Thus I decided to mount it in a relatively higher position on back of the Z extrusion rail above the PSU.

The enclosure is mounted with the sensor on the extrusion rail with 2x M3x8 hex screws and 2x M3 T-nuts.

The sensor is connected to my RPi which is built into an AIO enclosure on the back of the printer. To read out the temperature I use the Enclosure plugin for OctoPrint.

For mountig:

• 2x M3x8 hex screws
• 2x M3 T-nuts
• 4-wire Dupont wires The two parts are designed to fit tightly enough together, but still can be separated if needed.
  With my printer setting that works without problems.
  The bottom whole for the Dupont wires is just as big as needed. Squeeze the cables togehter to fit through the whole
