About this 3D model

What do you do when one of the keypad buttons on your door lock disappears?! ...3D print a replacement, of course! This button is designed specifically for the Schlage door lock model BE365 / BE365F. After printing it in flexible filament, draw on the number with a permanent pen, stuff some aluminium foil into the cavity, install, and use! Be sure there is enough aluminium foil to engage the circut board when pressed, but not so much that it is always making a connection (that would give you a dead battery). Here's a video of it in action: https://youtu.be/JLWk7bKw26w
