Details

Stop hunting for the right metric socket. This Tekton 3/8" metric socket tray drops straight into your Milwaukee Packout 48-22-8431 — print it, load it, done.

DIGITAL FILE ONLY — IMPORTANT
This listing is for the digital STL file only. Sockets, tools, and Milwaukee Packout case are not included. After purchase, you'll receive an instant download link — print it yourself on any FDM printer. Nothing is shipped.

WHAT YOU'LL RECEIVE
- 2 STL files (Left tray + Right tray) — delivered as a single ZIP download, instant access after purchase
- Both orientations included — print whichever side your setup needs, or print both to fill the full case
- Personal use license included (see license section below)

CASE COMPATIBILITY — IMPORTANT
✔ Milwaukee Packout 48-22-8431 (Low-Profile Organizer) ONLY

✘ Does NOT fit: 48-22-8436 (Compact Low-Profile) | 48-22-8430 (Organizer) | 48-22-8435 (Compact Organizer)
These trays are sized specifically for the 48-22-8431 footprint. If you have one of the other Packout models, message me before purchasing — I may have a compatible option.

SOCKET SET COMPATIBILITY
Complete sets (single purchase fills all 38 metric socket pockets):
SHD91211 — 3/8" drive, 6-point metric, 38pc, 6–24mm shallow + deep
SHD91212 — 3/8" drive, 12-point metric, 38pc, 6–24mm shallow + deep

Or pair shallow + deep separately to fill all 38 metric socket pockets:
SHD91110 (6-pt shallow, 19pc) + SHD91114 (6-pt deep, 19pc)
SHD91112 (12-pt shallow, 19pc) + SHD91116 (12-pt deep, 19pc)

⚠ NOT UNIVERSAL — Pockets are dimensioned specifically for Tekton 3/8" sockets. Other brands use different wall thicknesses and lengths and may not fit correctly. Message me before purchasing if unsure.

Check my shop for the matching SAE STL file, and for fully printed physical trays shipped ready to use.

PRINT SPECS
- Print orientation: Flat — no rotation needed
- Supports: None required
- Tested on: Creality K2 Plus
- Recommended material: PETG — a tough, heat-resistant filament; more impact-resistant than PLA, better heat tolerance for vehicle and garage storage, oil and grease resistant. PLA works fine for home use.
- Not sure if your printer's bed is large enough? Message me — I'm happy to confirm.

WHAT MAKES THIS DIFFERENT
✔ No-skip metric coverage — 38 pockets for 19 sizes from 6mm to 24mm, shallow and deep, with a dedicated labeled pocket for each
✔ Fits 6-point AND 12-point Tekton sockets — both point styles share the same outer diameter; every compatible set above drops straight in
✔ Sockets stay put during transport — pockets dimensioned for vertical carry, vehicle trips, and accidental drops
✔ Size labels embossed directly into the tray — find the right socket without pulling them all out
✔ No tools, adhesive, or hardware needed — tray drops straight in
✔ Print in any color — match your Packout, toolbox, or shop aesthetic
✔ Both Left and Right files included in a single ZIP — print one side or both

PERFECT FOR...
Perfect for automotive technicians, mechanics, electricians, contractors, and serious DIYers who need reliable, professional tool organization. Also makes a great gift for him, gift for Dad, or a self-print project for anyone who wants their toolbox dialed in. Ideal for birthdays, Father's Day, Christmas, or any occasion where the toolbox needs a little TLC.

FREQUENTLY ASKED QUESTIONS

Is this a physical product?
No — this is a digital download only. You receive STL files to print yourself. Nothing is shipped. You'll get an instant download link after purchase.

Will it fit my Packout?
This tray fits specifically in the Milwaukee Packout 48-22-8431 (Low-Profile Organizer) only. It does NOT fit the 48-22-8436, 48-22-8430, or 48-22-8435 — those models have different internal dimensions. Check the label on the bottom of your case to confirm your model number before purchasing.

Do I get both Left and Right files?
Yes — the ZIP download includes both the Left and Right STL files. Print whichever orientation your setup needs, or print both if you want to fill both sides of your case.

Will the sockets stay put?
Yes — pockets are dimensioned to hold sockets securely during vertical carry, vehicle transport, and drops. They won't rattle or shift in the case.

What printer do I need?
Any FDM printer with a large enough bed. Tested on: Creality K2 Plus. Message me if you want to confirm compatibility with your specific printer.

No — personal use only. Printed items may not be sold, shared, or distributed.

Good to know

  • Insert only — adapters, storage trays, tools and toolbox are not included.
  • Visible layer lines are normal. They’re part of how every organizer is printed, and they don’t affect fit or function.
  • Color may vary slightly from the photos, due to monitor settings and material batches.
  • Some socket slots may extend to the bottom of the organizer, depending on the geometry of the sockets. That’s a normal part of the engineered design, not a defect.
