This is a mount to connect to the rails of a drop ceiling and allow you to swivel and angle logitech z906 speakers. It can be used for other speaker types as well, though it may need some modding. I used the models from several other things on the site to help create this, they are as follows: 5.1 Speaker Wall-mount: http://www.thingiverse.com/thing:292822 Grundtal Spotlight Swivel Mount: http://www.thingiverse.com/thing:44917 Drop ceiling cable hanger: http://www.thingiverse.com/thing:27897 I may mod this some more after i get it printed out and tested. Maybe add a clip or something to keep the speaker wire looking nice and clean.Print both stl files with supports. Attach the rail mount to your speaker with a 6mm screw. Clip the base to your drop ceiling rail Then use a zip tie or pin of your choosing to attach the mount to the piece attached to the drop ceiling. I decided to push a piece of PLA filament through the hole and then used a hand torch with a metal soldering tip to push it flat on the sides to make it act as a pin. Its pretty stable. Then slide the rail on the back of your speaker through the slot on the mount.
