Travel Puzzle with case

Here is my design of a small travel puzzle including a case that closes securely with a magnet, and opens/closes using a filament hinge mechanism. Just clean up the holes a bit and insert filament carefully. Printing in different colors gives it a nice appearance.

You will need to use superglue and to fix and insert the 2 magnets (6mm diameter, 3mm thick) into the cavities. Check correct polarity first :-) 

As small pieces can be dangerous to small kids, make sure your kids are old enough when playing with this. Usage at own risk.
