GUARDIANS OF THE GALAXY INFINITY ORB MAGNET

I have taken the origional rim and cut out 3 10x5x3mm pockets.
Then you can insert 3 neodynium magnets ( 10x5x2mm cheaply bought on Prime ), just remember to align the poles correctly be before gluing into place.

The first one i printed with 2 pockets, and it wasnt quite strong enough.

Props to Tonyyoungblood!
