Fridge door lock

This simple little thing is meant to mount to a cabinet panel adjacent to a fridge door, to keep the fridge door closed when you want it closed, and to keep tiny humans from drinking the ketchup and salad dressing.
None of the mounting touches the fridge at all, so you don't have to drill holes in or stick adhesive to your fridge.
For safety purposes, this lock does not auto-engage when the fridge door shuts (like the old latching fridges) but needs the disk rotated toward or away from the fridge to lock and unlock. It can be mounted at a height that makes it easy to use for older kids, but unreachable to ketchup-drinkers.
You'll need 3 short screws about 4mm in diameter. The screw that holds the disk to the anchor can be tightness-adjusted to make the disk harder or easier to move.
Please scale by 10x to print as I am a failure at file unit sizes.
