This remix is a smaller version of the bracket that attaches to the Play 1. It requires a short 1/4 - 20 bolt (standard tripod thread). The idea with this remix is:

1. Uses less filament to print this
   “Hook” legs removed
   Curved wings removed
2. Relies on the mount bolt to hold the speaker

If you are comfortable with strength of a bolt in the mount hole on the back of the Play 1 holding this bracket to the speaker, this remix does away with the hooks that reach over and into the base. There is potentially a chance that the bracket can turn, but I feel this is a low probability once the bolt is tight. You could slip a piece of thin rubber or cork between the bracket and the speaker to give it some compression and to help hold, but this seems like overkill.

You also need to print the wall mounted part with which this thing mates.

Printed in PLA, .2mm layers, 40% infill.
Oriented it upright with supports under the pin hole for a clean ceiling of that bridge area. This sites at a slight angle on the bed which is fine, but the pin hole is round on the bed so the perimeters are circular and strong.

I mated mine with another remix of the wall bracket with the hole in the pin. This hole adds additional perimeters and space to insert a screw to hold the layers tighter if needed. Seems really strong as-is though.
