Magnetic Calendar Holder

This is a simple calendar holder designed to magnetically attach to your refrigerator, for example. There are 6 holes in the back, see the images to determine which is which.3 of them are 3.05mm deep and are designed to house three 10mm x 3mm circular magnets (Amazon Example)3 of them are 2.5mm deep and are designed for three 10mm x 3mm non-slip feet (Amazon Example), these should stick out slightly from the model to grip the magnetic surface like your fridge.The magnets give the holder strength to grab onto the fridge, but provide little to no sliding friction to avoid sliding down the side of the fridge. This is where the non-slip rubber feet come into play! With both of these friction-fit / stick-into-place items the holder seems strong enough to hold any normal sized (weight) calendar.
