Smart Fridge Chime Inhibitor

I've got an LG smart fridge (model LCFC26XSS) that chimes whenever one of the doors is open for more than 60 seconds. There's no setting to turn off the chime. This makes putting away the groceries very annoying.

This model is just a simple bracket that holds a couple magnets over the door sensor, causing the fridge to sense the door is closed when it's still open. It does have the side effect of turning off the interior light, but that's a small price to pay for not having to listen to that infernal noise.

Design

To test whether this will work with your fridge, take a magnet (I used an 18x5mm ceramic magnet) and run it along the top edge of the door opening until the interior light goes out. For my fridge, I had to do this very slowly because the light fades rather than just shutting off. If your fridge reacts when the center of the magnet is about 18mm from the top of the fridge, you're in luck. The attached STL will probably work for you. Otherwise, you'll have to do a custom design using the attached OpenSCAD source.

Printing

PLA if perfectly fine for this. It can be printed with no supports (ignore the overhang warning; that's where the magnets go).

The model is designed to fully enclose the magnets. You'll need to pause the print once the recesses for the magnets are printed, set the magnets into the recesses, then resume printing.

Usage

To prevent chiming, set the inhibitor on the top of the fridge with the magnets hanging over the edge so that they're in front of the sensor.

To store the inhibitor, attach it to the side of the fridge like any other fridge magnet.
