This version of the Hexagon Corner Bracket introduces a holder on the inside, that you can use to fasten cables. Or just run the cables along the inner corner and keep them there.

Quite handy when you are building an enclosure e.g. with LED lights on the top.

It has enough space to pull through thicker plugs.

The bracket prints nicely with the correct orientation of the holder. Make sure that it runs from the bottom to the top. Same with the hexagons: the sharp corners should point up to avoid bridges.
