Details
Print the organizer yourself. This is the 3D print file for our Tekton SID91211 organizer insert: the complete 3/8" drive metric impact set, shallow and deep, 6-point, 6–24mm, 38 pieces, every size labeled.
DIGITAL FILE ONLY
You receive a ZIP download right after purchase. Sockets, organizer and Packout case are not included, and nothing is shipped.
WHAT YOU'LL RECEIVE
- 3MF file: the whole organizer with the size labels and logo already in place as separate parts, ready for a two-colour print
- Two STL files (base and labels): the same design as two STLs, for slicers that prefer STL
- A Start-here card linking to our print instructions: recommended settings, plus how to split the organizer with your slicer's cut tool (Creality Print, Bambu Studio, Orca Slicer) if your bed is smaller than about 300 × 200 mm
- The license: the Mountaineer Maker Digital Product License (v1.0) as a PDF
FITS
✔ Milwaukee Packout 48-22-8431 (Low-Profile Organizer) and 48-22-8436 (Compact Low-Profile Organizer)
Built to the Tekton SID91211 set, with pocket sizes taken from calipers on the actual sockets. Shallow sockets stand upright; deep sockets lie flat in labeled troughs.
⚠ NOT UNIVERSAL: pockets are cut to Tekton SID91211 3/8" metric impact sockets. Other brands and sets may not fit. Message us before buying if you're unsure.
PRINTER REQUIREMENTS
- One piece, 293 × 193 × 41 mm. Your bed must be at least about 300 × 200 mm. It does not fit 256 × 256 mm beds in one piece.
- Smaller bed? Your slicer can cut it to fit. See the step-by-step print instructions for Creality Print, Bambu Studio and Orca Slicer.
- No supports needed: every overhang is designed at 45° or steeper
- Designed and tested on a Creality K2 Plus; we print ours in PETG
OPENING THE 3MF (two colours)
- If your slicer asks to scale to millimeters, answer No. The file is already in millimeters; the small label parts trigger that question.
- If it asks to load as a single object with multiple parts, answer Yes. That keeps every label in its recess.
- Every part loads on filament 1. Change only the BASE part to your second filament; the labels and logo stay on the first, and that's your two-colour print.
- A warning that labels are not on the surface is expected: they sit inside recesses on purpose. The colour changes are banded by depth on purpose to keep them few.
- Using the STLs instead? Import both files together without re-arranging, so the labels stay on their pads.
LICENSE
Personal use under the Mountaineer Maker Digital Product License (v1.0). You may print it for yourself and give prints as personal gifts; selling prints or sharing the file needs a commercial license or written permission.

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.
Compatibility
Same mating interface as the adapters — stacks on a shelving unit, a workbench, or a deep drawer.
Always check the label on your storage case or drawer to confirm the exact model number, and compare it against the compatibility chart above. Contact us if you have questions.
Precision-Fit
Designed from the actual sockets.
