Network Switch holder under the table

I wanted hold the network switch under the table and I made this design.

This is useful for small network switches (5 ports) and it is hold using a simple screw of 3,5mm (6 x 3/4")

I put a little hole for a M2 screw to adjust the height of the switch if the height is lower than 30mm.

The parts are 5 mm width to allow pass the air between the network switch and the table.

If you like it, please, comment and share your make.
