Magnetic Rim for "Guardians of the Galaxy Infinity Orb / Stone / Gem"

This is an alternate rim for tonyyoungblood's Infinity Orb - Thanks Tony!
(see https://www.thingiverse.com/thing:430184).

This version of the rim has recesses for installing magnets, which will hold the two halves of the orb together. Print two copies of this part; they are designed to fit together. Use eight, 10x5x2mm neodymium magnets.

This idea is borrowed from Jamie Taylor's modified rim - Thanks Jamie! (see https://www.thingiverse.com/thing:2312026). My variant repositions the magnets so that the two halves mesh together seamlessly.
