Made this for my mum. A print in place case for cigarettes with a magnet lock. No support needed. The small strips to hold the cigarettes in the case should be glued. 

It can hold up to 20 cigarettes. 

I made it for cigarettes of 180mm long. 

The Magnets are 5mm x 2mm. 
If you would like to make this, but have different magnets, I can change the size, just ask me.
