Case for NodeMCU, oled-display and BME sensor

thingiverse

This case houses a nodemcu v2 'Amica', a 0.96" OLED display and a BME280 sensor. The latter gets slipped into a pocket which is easy to seal off with a little elastic gum so the measurements are a bit less influenced by the controler's warmth. Everything else can be screwed in, I designed it for m2 screws (6x4mm, 4x14 or 16 or 20) The display is oriented by 4 pins while a stripe that is fixed with 2 screw holds the display in place. Adding screw sockets at the four corners of the display would have forced the display to go in for a mm or two and I wanted to avoid that. I designed the case for a bathroom thermometer that sends me a telegram message if I opened the window and forgot about it and the bathroom is getting rather cold - something that is useful for me in winter. Of course, the magic is in the software and not in the enclosure. https://github.com/planetar/bibbiGram Update: Designed a v2 version which aims to diminish heat issues. It adds lots of vents, the pocket is slimmer and has thicker walls and the sensor window is larger. The mcu sockets are pushed to the other side so the the top and bottom can be assembled so that the voltage unit is located away rom the sensor (instead of directly below). sperical feet on the top and bottom help assure air flow in and out. Pro: v2 significantly reduces distortion of temp and humidity values (~2°C at 21-23°C). Con: v1 looks 'cleaner' w/o all the vents. Anyway: this thing is not meant to be a precise thermometer, it is meant to act on changes of temperature or relative humidity. Distortion of absolute values has no impact on the precision of measuring changes. For some reason thingiverse preview doesn't show the _v2.stl but accepted a photo.
