Remix of my other upload “Wingspan Egg and Token Magnetic Storage Box”, but modified for Wyrmspan as requested by @CDAsh 

I used these Magnets from Amazon: https://amzn.to/3BQmz6m (you need 16) in combination with some cyanoacrylate based glue like https://amzn.to/3BTesWv or https://amzn.to/4gTlV6I, but other magnets with a 6mm x 2.75 mm form factor should work*

You have to be very careful about the polarity, which side of the magnet goes in, so that the box sections will attract and not repel.

* Please note that I linked a 6x3mm magnet from Amazon, this is intentional as upon measuring them, they seem to actually be about 2.75mm thick.
