Dog Seat Belt Button Guard

thingiverse

Those handy dog seat belts that clip your dog's harness securely to the seat belt latch have one fatal flaw: your dog can step on the button and release himself! (This has happened twice to me in the last week.) This minimal guard piece slips into the gap in the metal tab and covers up the seat belt button when the tab is inserted. There's still enough room to sneak your finger in through the side to reach the button.
