Wall stand for SONOS Play:1 with cable management

I wanted to mount an oldie but goldie SONOS Play:1 speaker in the kitchen. A plain shelf would have done the job, but the cable mess would not have disappeared - that's why I have designed this one.

I have uploaded two helper items too: 

• SONOS Play 1 wall mount marker.stl acts as a drill template
• SONOS Play 1 wall mount alignment template.stl helps you to fix the two dovetails parallel

I have printed it from eSUN's ABS+ with 3 perimeter shells, 15% infill, without supports.
