This is a follow on to PR #1103 that only touches testing. It updates file names on current 3D group tests. Since all checks pass, I am merging without a separate review. Please report any concerns.
Description
This is a maintenance update to bring the 3D group expected files names in line with the more recent ones. It uses 15-20 for ri rather than just 15.
