5x2mm Magnet Hide a key

Its a hide-a-key I made for a specific key for work. The inside hold dimensions are 45mm x 25mm by 3mm thick. It uses 5x2mm magnets in the corners. I use it to hide a spare key at work for my locker because I forgot my key once and had to break it open. Never again. Any print profile will work, it's a small print.
