I designed this bracket with a loop in the middle to feed the cables through. Hopefully, it will keep the cables tidy and act as a bit of a safety feature. If the Smart Hub is knocked off the wall, the loop should hold the cables and stop it from hitting the floor if mounted high enough. If the cables are tripped over, the loop should change the direction of the force applied, pulling the hub backwards and down instead of forwards. In theory, this should prevent it from being yanked forward off the wall and crashing to the floor.

What can I say? I am clumsy, and I need to factor in these sorts of calamities.

I also designed it with rounded contours in the hope that it would look store-bought at first glance and hopefully not hold a person's attention. Nothing worse than a 3D print sticking out like a sore thumb.

I have included the Step file so you can modify it as you please. I have also licenced this as public domain so it can be freely reproduced, distributed, transmitted, used, modified, built upon, or otherwise exploited by anyone for any purpose, commercial or non-commercial, and in any way, including by methods that have not yet been invented or conceived. You don't need to "remix" or attribute anything to me. If you want to print these off and sell them, as is or modified, go ahead.

P.S. All measurements are in MM.
