This is part 2 of a case enclosure for a 10’ LCD screen for a Marine Instrument & Display Controller. This file is a straight STL conversion from the 3D model which has been optimized for laser cutting. Although the model is mechanically correct, it still needs to be optimized for 3D printing. For more information have a look at http://www.hackster.io/mvandervoort/maritime-instrument-display-controller
You may download the STL file from here, 3D print it directly either from 3D Hubs, or on your own printer.
