Wall Mounted Filawinder laser sensor holder

I frequently see examples of users mounting their FilaStruders and FilaWinders on the wall, but I always see the sensor sitting on a shelf below them.

I took h0lger's laser sensor holder, at its default parameters, and added 2 mounting posts on the back. The laser is pointing toward the wall for safety.

The screw holes are extended through the front in order to make it easier to screw this thing into the wall.
