The keyboard on the computer table began to interfere with me, there was not enough space. I decided to make a shelf for the monitor. I used a shelf made of chipboard from an old chiffonier as a material. In the photo, it is walnut, just under my table. I sawed off with a hacksaw a tree too much: Length 86 cm, width 25 cm. I sawed out the supports, in the photo they are finished with white veneer chipboard material: length 25 cm, height 8 cm. The distance between the supports is 54 cm under the Logitech G 510 keyboard.
He fixed the supports with long screws, three per support can be seen in the photo.
In the photo, the keyboard is under the shelf. The table can be used as a desk, two compartments on the left and right. There you can put DVDs, flash drives for phones. Thanks to the shelf, the monitor has risen higher and is at eye level. I have a retractable shelf for a computer keyboard, but its place was taken by the KeyRig 49 midi keyboard.
