Based on Zack Freedman's Gridfinity "Templates.f3d" file.  Per a request I've modeled a holder for (5) 1/2 inch drive sockets.  Assumes a socket height of 38mm.  Any taller and they'll "hang over" the next Gridfinity space.

Edit 1/5/24: Increased the socket diameter by 1mm to alleviate the snug fit of the previous design.
