The components are mainly based on AirGradient DIY V4 but includes bigger OLED screen that can double as a Clock and 8 bit WS2812 Led that changes color based on different air quality measures

Assembly
- Assembling the protoboard itself requires soldering, you can use the attached photos as a reference for placement and the schema for the wiring
- Most importantly the placement of the OLED Display and Leds as they have matching cutouts/grooves in the faceplate
- Software is based on esphome (reference config file)
- Use the M3 screws to attach the faceplate to the proto pcb
- The case itself is a press fit on the faceplate (faceplate might require some filing around the corners to fit)
Filaments Used: eSun PLA+ Cold White, eSun PLA+ Brown
Note: This is a prototype version, there are some small modifications needed to make this case print better, the small gaps on the right side were a bit flimsy and didn't print with good quality but should be an easy fix and the thread holes could use an extra 0.1mm tolerance
