Built for your order. We lay out this insert from socket dimensions already proven in our Tekton SKT15101 SAE and SHD91211 metric organizers, then print it and test-fit it with the real sockets before it ships. The images are design renders of the planned layout, not photos of a finished insert.

What you're getting

One 3D-printed organizer insert, built for your order. Sockets, the ratchet, extensions, tools, storage trays and the toolbox are not included. The set's ratchet and 6" extension don't have a pocket.

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.

Not Universal

This insert is cut to the exact dimensions of Tekton's 3/8" drive 6-point chrome sockets in the SKT15301 set. Sockets from a different brand or set may not fit correctly.

Don't have this exact set? Message us — we build organizers specific to your socket set, using dimensions taken from the actual sockets. Same price, usually 7–10 days.
