I recently bought a surround sound speaker kit. The ONKYO SKS-HT690 5.1-Channel surround sound system. I quickly found that it is difficult to find wall mounts for speakers that mount on a "tripod" setup. So I designed one myself. this setup has roughly 55mm from the back to where the hole is. So if you have speakers that meet this criteria then this is the mount for you.

For super strong support I printed these at 80% infill and they feel super strong and sturdy. Even have some weight to them like a real store bought quality product. Print this with the screw holes flat on the bed and you will not need supports.

I designed these to be used with sheetrock screws. So if you use anything different you may need to adjust accordingly. Also, I provided a file for a washer that I had to use in my setup for the under side of where the screw goes into the speaker.

Otherwise, best wishes and good luck. :)
