This is a system for securing a device under the table with holes so it can be screwed in and held securely.
This way (as you can see in the photo) we keep the switch securely secured under the table, preventing falls or discomfort from cables.

Since it will be on for a long time, it has a special thickness to allow for some ventilation from the top (and so it's not too close to the table).

Orientation is important when printing, as what's printed on the same layer is usually stronger, so it's important to print it sideways so it can support almost any weight.

If the device is taller, you can simply scale it along that axis to adapt it to the height of your device. You also have an extra hole to use a screw to prevent the device from shifting horizontally, preventing accidental falls.
