Improved mounting mechanism for the rangefinder.

Neck_brace is a small piece of acrylic that mounts vertically up from Neck_top.
The side of Neck_brace fits snugly against an IC on the back of the rangefinder, safely holding it in place.

Additions to BOM:
-Neck_brace acrylic piece (1).
-M3x14mm machine screw (1).
-M3 machine nut (1).
