Power Brick Wall hanger

My kid received some LED strips for Christmas and wanted to put them up around the top edge of the room. The power cable has a large laptop sized power brick with a short cable. Instead of letting it hang off the cord (never a good idea), I put together this quick container to take the weight off the cable. there is a cut out in the bottom of the cup for the other side of the power cable. I am sure this could be used for a variety of laptop power bricks as well. Internal dimensions are 31mm x 52mm. Screw holes have a slight taper to them so that the screws are more flush with the back panel.
