Synology RT2600ac Wall Mount Adapter

Lovely router by all reports (I haven't actually set it up yet), but the steep angled legs make the built-in mounting slots rather ridiculous. They're an inch away from the wall and tilted at about a 26-degree angle.

CAUTION: Synology's instructions for this router say simply to place it on a flat surface and make no reference to the keyhole slots underneath. There is also a safety note, "Place the product right side up at all times." Possibly I'll have gone to all this trouble just to cook my router. I doubt it, but if yours overheats and you think it was because you put it on the wall, do let me know!

(I have so little flat surface available between computers, ink printers, 3D printers, a solder rework station and bookshelves, I'm willing to risk it.)

UPDATE: Over a year later running 24/7 on the wall, no hint of any distress, thermal or otherwise, and we've had some 80-degree days (not hot enough to bother putting the air conditioner in the window, but well over normal office room temperature).
