We would like to reduce the size of control box so we could free up almost all the space on the table and the user could enjoy a bigger work space.
We would also like to use better focusing and lighting mechanism next time because the current hardware felt really under powered. The single LED mounted will be replaced by a better light source, like LED strips or multiple LEDs.
And in the final product, we are planning to have a better structure and use something rigid than corrugated boards because corrugated boards tend to break and don't give an aesthetic sense to the end user.
