I just wanna put RPi temperature and humidity monitoring to the rack. Original case looks okay, I just change the holes for classic M6 screws, and added some mounting holes for OLED display and temp&hum sensor.
Display used: SH1106 (very similar like SSD1306, but 1.3" instead of 0.96")
Sensor used: HTU21D
Both uses i2c bus, so it is very easy to connect them (parallel)
Connected to Pi:
1 - VCC
3 - SDA
5 - SCL
6 or 9 - GND
Sample Python code for sending data to great TMEP (tmep.cz or on github) is here: http://wiki.tmep.cz/doku.php?id=zarizeni:raspberry\_pi#raspberry\_s\_htu21df\_a\_oled\_displejem]

The author remixed this model. Imported from Thingiverse.
Added screen and sensor mounts.
