Ubiquiti has recneltuy launched the new Cloud Key Stand for the UCK-G2-Plus. This is a simple metal stand, which should allow the Cloud Key to get better ventilation, as this device does get pretty warm. It is up now on the official Ubiquti Store in the US and EU for $19 US, €21 EU and £18.65 in the UK.
As you can see in the photos, the Cloud Key mounts on its side, but unfortunately the screen is orientated the wrong way. There is no way of changing this in software just yet.
