Dell Monitor Stand U2412M / U2312HM

This stand perfectly fits for Dell Monitors U2412M, U2312HM or similar (with the same stand).
It increases the monitor's height by about 3 cm and is shaped similarly to the base that makes it look like one piece.
In the front there is a cutout for storing small things.

The connecting pieces have a very tight fit, so if you can't join them, take some material off until you can put them together.
