I've been wanting to build some type of container for my Ardiuno/LCD combination for some time. A couple weekends ago I finally bought some plexiglass and machine screws and made it happen.
The plexiglass is more fragile than I expected. It's extremely scratch prone and cracks easily with just a slight bit of pressure. Scoring and snapping was actually the easiest part of dealing with the plastic. Drilling holes produced small cracks on more than one occasion.
Eventually I got it right and now the Arduino and its components have a solid base to function on.
