Milwaukee M12 tool wall mount

Wall mount for the Milwaukee M12 tools. Main improvements over the [remix source](https://www.thingiverse.com/thing:4765913): * Rotated the hold by 90degrees so the tool is now parallel to the wall it is mounted on (allows larger tools to be mounted) * Increased wall mount height for more support and easier access to the top screw * Increased diameter of top screw, plus screw now completely sinks in
