This is to use with @Jacaeiro's excellent RPi 4B case. The standoffs screw into the back of the front part. With long enough screws, probably can use the back, but I chose to leave it off for additional air flow (and since I wouldn't really see it).

I used Gorilla Tape to secure this to my cabinet. That stuff is very strong.

Since it sags a little because of play in the hinge, I included a little 'ledge' I used to help keep it more level when it's in place in front of my cabinet door.
