LED channel joiners corners

This is my design of various joiners and corners for v-shaped LED aluminium channels.I used them to hang my LED under the soffit of my roof without destroying too much in the way - thus the slide-in friction clips plus few screws.
You may have to tweak its sizing to fit your channel as they are not all the same.
