Gridfinity Socket Organizer
A gridfinity socket organizer turns a tangle of metric and imperial sockets into tidy rows of round pockets. Enter each size as a diameter, a depth and a quantity, watch the layout fill the 42 mm community grid, and download a printable STL. The block carries the standard foot underneath, so the finished gridfinity socket organizer clips into any baseplate like a bin — no glue, no screws, no measuring.
The difference between this and a plain bin is geometry: a gridfinity socket organizer cuts real round holes — cylindrical pockets sized to each socket — instead of square compartments that sockets rattle around in. Rows are defined per size, so a mix of 12, 16 and 20 mm sockets lands in three distinct pocket rows on one block, and the suggested grid grows automatically as counts rise.
Every pocket is blind: it stops on a solid floor and never pierces through, so sockets rest on real material and nothing slips into the drawer below. The file behind the gridfinity socket organizer is generated locally in your browser, checked for watertightness before the download unlocks, and completely free — no account, no upload, no print limits.
Why sockets need a dedicated gridfinity socket organizer
Square gridfinity bins hold screws and hex bits happily, but sockets are round, nested cylinders — drop a 12 mm socket into an open bin and it disappears under its 20 mm sibling within a week. A gridfinity socket organizer gives every socket its own sized pocket instead: each row of the layout is one diameter, one depth and one count, so the tool packs the block tightly rather than leaving dead air around every round part. The finished gridfinity socket organizer prints in one piece and rides the same plates as the rest of the system, and because it is parametric, a gridfinity socket organizer regenerates the moment your set gains a size.
What the gridfinity socket organizer tool includes
Building a gridfinity socket organizer, step by step
- 1
List your socket sizes
Sort the set and note each diameter, how deep the pocket should be, and how many of that size you own — the gridfinity socket organizer turns that list into rows.
- 2
Enter diameter, depth and count
One row per size. The gridfinity socket organizer accepts diameters from 4 to 40 mm, depths from 2 to 20 mm, and up to 60 pockets per size.
- 3
Accept or adjust the grid
Read the cell count the gridfinity socket organizer suggests, then nudge X or Y if the block must squeeze onto a crowded plate.
- 4
Download and print
Export the STL, print it pocket-side up, and click the finished gridfinity socket organizer into its plate.
A worked example: a gridfinity socket organizer for 12, 16 and 20 mm sockets
Here is how a mixed set maps onto the rows of one gridfinity socket organizer block. Depths should roughly match how far up the socket wall you want support; measure your tallest socket and keep every depth at or under the 20 mm ceiling. Counts come straight from the set you own.
| Row | Diameter | Pocket depth | Quantity |
|---|---|---|---|
| Metric small | 12 mm | 14 mm | 6 |
| Metric mid | 16 mm | 16 mm | 4 |
| Metric large | 20 mm | 18 mm | 3 |
Feed those rows to the gridfinity socket organizer and the suggestion engine sizes the block in whole cells: the footprint follows the familiar rule of cells × 42 − 0.5 mm, so a suggested 3 × 2 block prints 125.5 × 83.5 mm regardless of what is inside it. If the rows will not fit, the tool says so before anything prints — enlarge the grid or trim a count.
The foot: how the gridfinity socket organizer stays put
Underneath the pockets sits the community gridfinity foot — the same 4.75 mm tapered profile every bin uses, on the same 42 mm pitch. The organizer therefore behaves like any other gridfinity part: it drops into a baseplate socket, resists tipping when the drawer slams, and lifts out when the layout changes. A gridfinity socket organizer built this way is simply another citizen of the grid, free to migrate between plates as the workshop evolves — which is exactly why a gridfinity socket organizer belongs on the same plate as your bins instead of loose in the drawer.
Print settings for a gridfinity socket organizer
PLA or PETG at 0.2 mm layers with two perimeters handles the pocket walls well, and 15 % infill keeps the floor solid under metal sockets. Print the block pocket-side up so the blind floors stay smooth and the cylindrical walls need no support — even 20 mm pockets print cleanly because each wall is one continuous vertical tube. If a socket binds, add 0.5 mm to that row's diameter and regenerate; that is the advantage of generating your own gridfinity socket organizer instead of downloading someone's fixed file.
Depth is where taste lives. Shallow 8 to 10 mm pockets grip the drive end and leave size markings readable, while deeper pockets hold sockets fully but hide them. The gridfinity socket organizer regenerates in seconds, so try both before committing a whole plate.
Beyond sockets: one gridfinity socket organizer, many round tools
Any round stock inside the limits can ride the same geometry: hex driver bits, step drills, dowels, short pencils. As long as the item is round, between 4 and 40 mm across, and needs no more than 20 mm of pocket depth, a gridfinity socket organizer row will hold it with the same blind-pocket cleanliness. Pair one organizer block with open bins on the same plate and a drawer handles loose screws and precision tools without letting them mix.

Frequently Asked Questions
What socket sizes can a gridfinity socket organizer hold?
Any round item from 4 to 40 mm across, in pockets 2 to 20 mm deep, with up to 60 pockets per size row. Standard metric and imperial socket sets sit comfortably inside those bounds.
Do the pockets go all the way through?
No. Every pocket on a gridfinity socket organizer is blind — it stops on a solid floor and never pierces the block. Sockets rest on printed material, and nothing falls through into the drawer below.
Will it fit baseplates from other gridfinity tools?
Yes. The block carries the community foot profile on the standard 42 mm pitch, so the gridfinity socket organizer drops into any community-standard baseplate, including plates printed with other generators.
Can it hold tools other than sockets?
Anything round works: driver bits, dowels, pencils. The gridfinity socket organizer simply cuts blind cylinders to the diameter, depth and count you type.
