Step 4: Mechanical assembly - attach display and enclosure
To plug the board into the display, gently push the board into the connectors, after you properly aligned them (photo 3).
Next step is to attach the simple enclosure, which is made of a pair of plexiglass plates, either 3mm smoky or 4mm clear, with the dimensions shown in photo 4. The DXF file, used for laser-cutting, is available for download here .
The 2 plates are directly attached to the display, with the standoffs in the four corners. (The board fits snugly between the display and the back plate and does not need any other attachment or screw.) The longer standoffs go in the back of the display, and are screwed into the shorter standoffs placed in the front of the display. Note that the 4 washers provided are to be placed on the back of the display, between the standoffs and the display's board, essentially extending the longer standoffs.
The final assembly looks like in the last picture (photo 5).
