Fun key ring attachment if you don't like wearing the traditional magic bands.
just pops right into the design provided.
Made the inside concave to perfectly hold and surround the little fob that is removable from the magic band 2.0
Used the ring feature in tinkercad, modified the dimensions to fit the rough outer diameter of the fob piece. ised the adjustment tool to create a nice round shape with concave interior to fit the fob.
Added a small circle to act as the portion to feed a keyring though. Then just grouped and exported as STL
