The TC420 and TC421 are very nice and relatively cheap LED controllers for fish tank / aquarium lights. However, there is no cover at the connections, so I created a two-piece cover.
The lower part will be screwed in permanently. The upper part will only be held by two screws, so you can still reach the ports effortless.
PS: the “rear bracket” is totally optional. It's just helpful, if you try to screw on the controller to a cardboard or similar thin walls.
