Echo Buttons are much more useful than you might think.\u00a0 They can be used to play games but they can also be used to control your environment and make announcements.\u00a0 In one facility serving people with disabilities, echo buttons are used to initiate Amazon Alexa routines that vary from turning on and setting the temperature of a smart oven to announcing that a client needs help in one of the bathrooms.\u00a0 There’s already a design for an Echo Button mount on Thingiverse<\/a>.\u00a0 All we did was to extend the housing for stability, add a lever arm and a fulcrum for the arm to attach to.\u00a0 The result looks like this:<\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

The final print is comprised of five pieces.\u00a0 A housing that serves as the base that sits on a horizontal surface or screws onto a wall, a screw-on retention ring, a lever arm, a small bumper, and two semi-circular posts.\u00a0 The two semi-circular posts can be glued together to create a cylinder or can just be left as is and inserted into the arm assembly hole together.\u00a0 They’re designed and printed as halves of a cylinder to make them as strong as possible without requiring the use of supports.\u00a0 The bumper should (optionally) be printed using a flexible filament to protect the plastic face of the button.<\/p>\n

\"\"<\/a><\/p>\n

The bumper glues into a circular recess on the underside of the lever arm.<\/p>\n

The STL files for this device can be downloaded from Printables<\/a>.<\/p>\n

The arm provides an approximate 3.5 to 1 mechanical advantage.\u00a0 Normally, it takes about 700 grams of “force” to activate the button.\u00a0 With the lever arm, it takes only 200 grams of force.<\/p>\n

To change the batteries on the echo button you can swing the lever arm back and unscrew the retention ring.\u00a0 If the arm is still in the way and prevents you from unscrewing the retention ring, just slide the attachment post out and remove the arm entirely.<\/p>\n

Do you have any ideas about how to improve this design?\u00a0 Provide some information below:<\/h1>\n
