The CDU bay was made from 12 mm MDF. I used this instead of the 10 mm sheet I had to give an additional support to the main instrument panel. With the bay under it's center it feels very sturdy. After all the measurements are made to ensure that the parts will fit unter the MIP, the construction is very simple. Only some more pieces of wood were needed to connect the two siede parts to a box.
The front was covered with 3 mm HDF. Screwes were used to give the possibility to remove the front plate to make it easier to install the CDUs or the lower eicas later.
