This weekend I made a set of speaker mounts out of plywood, a bunch of bolts and nuts, and some knobs I made with the 3D printer.
It can be tilted in two axes. It's certainly not the simplest way to design a speaker mount and it is a bit bulky, but that's all intentional. I like the way it looks with the two knobs and the home-made look of the plywood. I have other store bought speaker mounts that use a ball that rotates in three axes which is much simpler, but these are really hard to adjust. Also, the third axis of rotation is not really necessary anyway. With this mount is really easy to tilt the speakers by just loosening one of the knobs, tilt, then tighten again. This project is also a bit of an experiment.
This is the 'arm' of the mount. I used a t-nut here to be able to tighten this first screw. All is made out of 1/2 inch plywood. I also used a screw to go across the back side of this arm to provide extra support on top of the carpenters glue.
And that's how it all looks put together. I used the same 3D printed knobs I made for this project. The finish here is terrible, there're some burn marks on one side of the face plate but I'll take it all apart and give it a sanding and a couple more coats of lacquer.
