This is made to hold the Hypertough ¼" Ratchet and socket holders in a 2x4 Gidfinity Bin, the bin is 3 tall, but no where near tall enough to cover the deep well sockets to be stacked.

It was printed in PETG on an Ender 3.  It is a tight fit to get the socket holders into the depressions, the bottom of the socket holders is hollow, so they may need a small screwdriver or such to push them inward at the edges if they catch a bit.  They fit flush when fully inserted, and for me are very snug.
