Bracket for shelves caravan

Here I designed and printed a small bracket (double screws) for my caravan Knaus Sudwind shelf.
One morning I had the bad idea to grab the shelf over my head for helping myself in standing up....just heard a crack and afterward saw the shell in one strange position...shocked!
The shelf fixing collpsed and there was no way to restore it, so I decided to put one bracket under the shelf ...
