This is a Customizable wall mount cradle. There are several options, feel free to comment if you need clarification for each one. I built this for a specific purpose for myself, so some aspects are hard coded, like the power cutout on the side is centered on the side panel and not "positionable", although I did make it so that it could be switched to either side or not at all.

I also have uploaded example pictures of a cradle as well as examples of what some of the option outcomes look like (rounded/square corners, beveled/flat screw holes for mounting).

UPDATE: Barely a day later and I come with an update. I printed the cradle for my USB charger and it looks and works great for our need, however I realized quite quickly that some uses may require a bottom set of mounting screw holes.The USB ports are on the bottom front, and when I remove/insert USB plugs the cradle flexes away from the wall due to only the top set of screws. I am going to just drill my bracket, but updated the .scad file to allow choosing top, bottom, both or none for mounting screw locations. I also adjusted the vertical placement algorhythm so that they are spaced mid-way between the back cutout and top/bottom. This is even if you do not choose to include a back cutout, the calculations still occur on the back end, so no worries there. And I cleaned up a Customizer menu option that was incorrectly labelled in my code. I also uploaded a screenshot of what a 4-hole mount would look like.
