At our shop we have a TV projector and a Wii with a third-party battery powered IR lightbar. I wanted to mount the lightbar on the wall just under the TV projection, so I made this bracket to hold it.
[upate: New STL file uploaded, rotated onto its side to make for a much stronger build. I managed to break the bottom off of the first one along a layer boundry while mounting it to the wall. Superglue fixed it, but it's better if it isn't needed!]
