Created the model from scratch.
Idea is to create a Coin Organizer as gift for upcoming valentine.
It has slot inside for the magnets.
I left the top cover clean, 
So you can modify the front part easily,
Add text or image or anything you want for customization.

Magnet Size should be 10mm x 1.6mm, you need 2 pcs of course

Feel free to use / modify. 
I have the original project file.
