My three year old PreSonus Eris 3.5BT speakers died, so I made and printed a replacement.

The main model requires that you manually drill mounting holes along the edge. Use the original screws for this as well as mounting the electronics. I've also modeled an optional plug for the slave speakers, but I ended up just re-using the old plug myself.
