OLED and PIR Sensor Module

A friend asked me if I can adapt for him the popular case for raspberry pi (see here: https://www.printables.com/model/106225-modular-snap-together-raspberry-pi-2b3b3b4-case-w-) to allow for an 0.96 OLED display, his PIR sensor and external temperature and humidity sensor.

So, starting with the plain module, I made it taller (+14mm) in order to accomodate the PIR sensor. I also had to adapt for the OLED display I had (not all 0.96 OLED display have the same dimensions, make sure your fits!), added slots for CSI/DSI cables and for improving the airflow. On the sides, the backpack has two holes for adding external sensors.

The OLED display is glued, no screws are requred. For the rest of the parts to build the complete raspberry pi case, see the original model.
