Streamlined Contour to GoPro Mount Adapters

Summary Streamlined low stack height mount adapter allows Contour cameras to use most GoPro mounts. Cleaned up, made prettier and now uses less plastic. The print_test files breaks it up into two parts that can be welded together with a few drops of acetone (if printed using ABS). Combined the inline version with the 90° version into one Thingiverse entry, files are still separate. Small adjustments made to dimensions of the T portion. Instructions FreeCAD. Not sure if the GoPro section is far enough away from the Contour camera body, needs testing. Works perfectly.
