To give a nice commercial product look, I have designed an enclosure for this project by using Autodesk Fusion 360. The dimensions of all the components and PCB mounting holes are measured by a vernier caliper then the same were considered during the design.

The enclosure has two parts: 1. Main Body 2. Top Lid The

The main body is basically designed to keep the PCB board. The top lid is to cover up the main body opening and mount the OLED display.

I used my Creality CR-10 printer and 1.75 mm green PLA filament to print the parts. It took me about 6 hours to print the main body and around 2 hours to print the top lid. My settings are:

Print Speed : 60 mm/s

Layer height: 0.2mm ( 0.3 also works well)

Fill Density: 20%

Extruder Temperature: 200 deg C

Bed Temp: 60 deg C
