Two supports carry a board with a thickness of 18mm. A Kallax compartment can thus be divided evenly into three compartments. The width of the board must be approximately 33.1 mm. However, it is better if the board is slightly wider.
Thanks, this is a good update to other similar projects, that have little errors for me for example the thickness or left/right version needed and also a reinforcement that didnt allow to use the full height. Here is everything perfect and i resized it to 20 cm to insert the shelf in the middle, this size is done in 1 hour in normal mode with A1, thats also a good time.
Great Job
