Onkyo SKR-548 rear speaker stand

After having moved, I no longer had a wall behind my couch to mount the rear speakers of my Onkyo 5.1 sound system (model SKR-548), therefore I did that.

It's made to be printed as is, without support. Fits on a CoreOne bed. It is fitted with a Ø25mm hollow tube in which I threaded M3 screws (top and bottom parts), as well as places to pass the cables through the tube so that no cables are visible.
