I made a few different designs for the screen framework. the first relied on being fixed to the side panels of the icade, this although worked, meant it was difficult to take apart again.

my final designs were drawn on CAD and laser cut, purely because I could not achieve an accurate surround for the screen and the tolerances were so small.
the frame is made of 3mm MDF and glued with PVA and then hot melt glued in the corners to add strength.

The lid section of the icade has a 4mm wide groove cut underneath to allow the Perspex marquee to sit in to create a tight seal. two pieces of perspex sandwich an inkjet printed marquee graphic.

the speaker sections is merely a rectangular piece of MDF with laser cut speaker holes.
