This Magic the Gathering Dragon Egg Card Box will impress your friends. This design is a remix from the Dragon Egg on Thingivers (https://www.thingiverse.com/thing:3887093) but I am unable to find the original model on Printables as I believe the maker hasn't uploaded it here. I am uploading this for anyone interested in making a cool card box for your commander set.

For the magnets, you will need four (4) 0.47 x 0.12 inch neodymium magnets. This will ensure that nothing will fall out once the eggs halves are placed together. Pair that with a little bit of super glue and you will be good to go. I made sure to leave the tolerance of the box really loose in case it came out a bit tight, but not to worry, the magnets hold the top and bottom together perfectly.

No supports needed for the bottom unless you want to make sure the overhang doesn't mess up. Definitely need supports for the top if you print it flat on the build plate.

MAKE SURE YOU LAY OUT THE MAGNETS BEFORE YOU GLUE THEM DOWN. YOU DON'T WANT TO GLUE OPPOSITE ENDS TOGETHER.
