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.
