I made this mount to attach an Echo Dot to my square-metal-tube gazebo so it stops falling down and hanging from the wires when the wind blows. The design is heavily inspired by rjelbert's Echo Dot cup holder mount.

This model will print on its side as rendered without support. I had to slow my printer down a bit to get the quality where I wanted it. Going slow enough to look good, this model took about 4-hours to print.
