Cover with passthrough close button for liftmaster / chamberlain 877LM garage door keypad

My garage door keypad, an 877LM, can close the garage door just by pressing the enter button, no code needed. When I walk the dog, or take a car not parked in the garage, I want to easily close the door on the way out, and was annoyed with the inconvenience of opening the original cover, and it not always closing all the way.

So I redesigned the cover, and added a passthrough button to hit enter from the outside while the cover is still closed.

source scad file is included if you want to remove the button and just print a replacement file.
