These fit 3/8" drive metric Impact socket sets. These will hopefully work for you if you have a set that matches one of the combinations below. Note that normal sockets and impact sockets have different dimensions; if you are looking for normal sockets I have a separate model posted for those.

In the print profile pick the set or sets you want to print and whether you want the left or right hand labeled version. Color change is at layer 91 with the standard 0.28mm extra draft profile, or use the profile I uploaded.

Check the hole sizes by either by measuring hole sizes or move the blocks partway through the build plate (so the first layer has the holes in it) and print just a couple layers.

If these don't work for you you can make something similarly sized for your specific sets with the parametric files here

The bottom is 21mm gridfinty squares which are compatible with the standard 42mm grid.
