A small case for your medication or other small items.  
Consists of two parts: the lid and case itself. 

There is also a hole in each part for magnets (3x1.5mm). Magnets are not required! 
The lid closes good by itself but it might get worn out by using it a lot depending on your material, so just in case i put those there so you won't need to print another one and just add some magnets.
