5. Final Design Development

Hi! Today I am going to show you my final design concept and its development. My design process depends on various different factors such as the deadline date, if I have a clear vision of a product in my head, if it is a complex product with lots of components and complicated assembly etc. 

For this project we are required to use Fusion 360, which is one of many CAD software available on the market, however Fusion 360 has a great potential to be the software of the future. What I mean by that is Fusion being more recognizable and favourited by the companies and employers thanks to its unique functions, intuitive user interface (UI) as well as simplicity and being enjoyable to use.

My Idea was to create something very simple containing least number of components that would be easy to use, quick and cheap to manufacture and functional. 

The enclosure consists of two main components, which is the base, the biggest part where the board is screwed in place. On the left side of the base there is a huge gap and its purpose is to create easier access to SD card slot. On the opposite side there are two symmetrical holes for additional ventilation, I used 45° angle as 3D printer can print it without using the additional support therefore reducing the material and time spent on cleaning the enclosure. At the front you can find the standard access holes for USB and micro USB ports. Inside of the base there are four cylinders used as a support and placing method for the board, which can be screwed using 2.5mm screws. On the bottom of the case there is added additional material, which nicely stacks on top of the groove on the top part of the enclosure. Second component is the top/ lid that is attached to the base by simple sliding mechanism.
