This model stores the Harbor Freight 1/4 in. and 3/8 in. Drive Star Bit Socket Set. Sockets are oriented vertically at 90 degrees with ample support around them to ensure they don't fall out when shutting drawers.

Torx socket sizes are labeled in recessed lettering within the socket storage holes.

Thanks to Zach Freedman for sharing the gridfinity standard, and open source file used to create this design.
