The filter does not include the top rim. You need some rectangular wooden strip about 2-3cm in size to glue around. The x and y are without this rim and should be about 5 cm smaller that the nominal size.

The following sizes are currently hard coded:

Height of rails on top: 50mm
Borders on top: 40mm
Char coal width (horizontal): 40mm
Bottom width: 40 + 20 + 40 mm

For assembly it is important that all bottom plates are the same way up. This allows the ribs of adjacent pockets to pass beside each other.

There are three type of ribs:

Those with staight tops go in the middle of the bottom plates
Those pointier angle go at the outer sides and meet with the side bars
The less pointy go at all other sides of the bottom plates that will end up on the inside

The last two types of ribs do not have finger joints on the outside but still need to be glued to the top beam of the adjacent pocket or the left or right side bar.
