Magnetic Key Fob Case for vehicles

I designed this magnetic key fob case for my Chevy Equinox, but it should hold most fobs. My fob is larger than many others, however, it can be scaled up if needed. The slide-locking lid works best if you add a little Vaseline or other lubricant BEFORE sliding it into the case for your test fit. The case internal measurements are 35mm x 64mm x 19mm. The magnets were purchased on Amazon and measure 60mmx10mmx3mm. It needs 2 magnets side-by-side as pictured. They are a snug fit. After inserting the magnets, I put a little sealant over the top to prevent them from falling out when the case is turned over when retrieving the key fob. The outside wall where the magnets sit is only 1mm to maximize attraction while still providing adequate rigidity. As pictured, there is a small tab that extends from the lid to assist pulling it out as it fits firmly like a glove and could be difficult for some with weaker hands to remove without the pull tab. DON'T FORGET TO LUBE BEFORE YOU SLIDE THE LID ON THE FIRST TIME! If you don't, it may be extremely difficult to remove.
