Wand Vibrator Wall Mount

Thought I could make some slight improvements to [dasNessie's](https://www.thingiverse.com/thing:5973909) mount for Hitachi wands, so I changed a few things:

-Thinned the prongs for better compatibility with other brands of vibrating wands that don't tend to have such a large gap between the head and wand, which means it should fit both full-sized wands and the smaller, roughly hand-sized type, too.

-Removed most of the back wall where it wasn't as necessary since I changed the mounting to use screws rather than 3m/double sided tape

-Added a couple reinforcing bits between the wall and the prongs, just in case

-Added little nubs on the ends of the prongs just to help retain wands

For printing, I recommend 25%-35% infill, just for structural integrity. It is a wall mount after all, and be careful not to screw it in too tightly as it might snap the walls of the print along the layer lines.
