The design is simple with all functionality included.It comes with a glass outer case for protection from dust and other pollutants which would eventually reduce the contact between various electronic pins.The outer case could be made with hard plastic for more security & rigidity.
All the ergonomics included with proper spacing of the features used mostly.weight distribution also considered by placing heavier pins in middle and as low as possible. suggest me for any further improvements.constructive comments and suggestions welcomed.Thank you.
Revised versions will have more features and updates.Stay Tuned.
