LACK BME280 sensor mount for Ender 3

thingiverse

This is another sensor mount for my Ender 3. See here for my previous one: https://www.thingiverse.com/thing:4597337 I made another one, because i was not satisfied with the laginess of the AM2302/DHT22 on the RaspberryPi. This mount encloses a [BME280](https://amzn.to/3iPkkBo) 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.
