Logitech Z-150 angled wall mount

I use Logitech Z-150 speakers at work as part of an exam timing system, usually just placed on a table or the ground for when they are used. This isn't a sustainable or safe solution, so I have remixed Zedii1's Monitor Stand STL to remove the stand portion (maintaining the clip). Two of these are positioned with a 90 degree angle, with a rear plate and bracket for wall mounting (using screws). At the base there is a hole to allow power and audio cables to pass through if required. This is quite a niche use case, but will now allow the speakers to be safely wall mounted and provide adequate coverage in classrooms and hallways for timing messages to be played.
