Holder for the Pittsburgh (Harbor Freight) Metric (Allen) 3/8" and 1/2" drive socket set, part number 67880.  Gridfinity compatible, 1U (W) x 5U (L) x 3U (H).   Has nibs at the bottom to help avoid dropping in sockets of the wrong drive size.  Model is AMS ready.  I print all of my socket holders in PETG, but PLA will probably do the job.  Matches my SAE holder, shown in black in the photos, from the same series.

My design specifications:

• All holders are 3U deep for a uniform look.
• Must pass a drawer SLAM test.  (I use my tools, not just look at them.)
• Left to right layout with smaller sockets in the front.
• Clear label for the entire set in the upper left corner.
• 0.8mm hole clearance around all sockets for easy insert/removal.
• 1.5mm border around all holders.
• Clear labels that are 0.4mm nozzle compatible.  Font is Arial Narrow, bold, 5mm tall if you want to make something to match. 
• Beveled/filleted edges to make sockets easier to insert.
• Include holes for 2mmx6mm magnets, but I personally don't see the need.
