This is a replacement button for the Sparkfun 35mm Concave Button (https://www.sparkfun.com/products/9339), making it about 5 inches wide. It makes a fun giant button on the top. I debossed a logo onto it for our purposes, but can be used for many purposes.
Instructions
Just pop out the actual button from the bottom of the Sparkfun 35mm concave button, and squeeze the two pegs on the end of the plastic "button pusher", sliding it out of the casing.
Put the spring inside the new 3d printed button, and squeeze pegs together as you slide it back into the casing until it snaps in. Replace the actual button in the bottom, and you are good to go!
