Big Pushbutton Base / Enclosure

thingiverse

This is a base for Sparkfun's line of Big Dome Pushbuttons (https://www.sparkfun.com/products/9181). I printed this with ABS and the pushbutton snaps right into the top of the ring. There are several configurations you can print, including a basic base for the pushbutton or a ring with two built-in brackets for 8 ohm speakers and a base with a hole for a slide switch. The bottom is attached to the ring by two M3 screws: https://www.mcmaster.com/#catalog/124/3077/=1c12237. The slide switch attaches with hot glue from the inside. The entire switch, including attachable wings, should be no bigger than 20mm x 8mm and the actuator length should be 4mm or shorter. I used a switch I had on hand and can't recall where I purchased it. #### Audio Button Project For my project, I connected the big pushbutton to the Adafruit Audio FX board via a Push-button Power Switch breakout, two round 8 ohm speakers and three AAA batteries. Then suddenly I had a self-contained speaker box that plays an audio file when the button is pressed. * https://www.adafruit.com/product/2217 * https://www.adafruit.com/product/1400 * https://www.sparkfun.com/products/9151 * https://www.digikey.com/product-detail/en/mpd-memory-protection-devices/BC3AAAW/BC3AAAW-ND/863319 The only thing I would do differently is add a small Arduino, like an Adafruit Trinket, to send a kill signal to the Push-button Power Switch breakout after the audio has finished playing.
