This is a custom Gridfinity bin for the Rayban Meta charging case.  This bin allows for a USB-C cable to be glued into place so that you can charge your Rayban Meta while in the bin.  This is a great addition to a bed side Gridfinity installation for charging your glasses overnight.  This bin is also set up for magnet use with Gridfinity.  It is a friction fit for 6x2mm magnets, just hammer in, no glue necessary.
