No my design,

Reuploaded it from electronsmith https://3dprints.electronsmith.com/milwaukee-packout-socket-holders/

Author:

These socket holders are modeled after the ones found in the Milwaukee Shockwave Impact Drive and Fasten Set #48-32-4408. They can be printed to fit both 1/4″ and 3/8″ drive sockets.

I have made some improvements to the holder. First rather than the socket drive square being able to move freely, it is restricted to the down position and the open (45°) position.

This also makes it much easier to put the socket back on the holder. Second I have given you the option to use the grooves rather than pins.

There are three parts that you need to print: the holder, the drive square, and the pin.  

I’ve uploaded zip files containing all the correct STL files to create the holder specified by the file name.

I’ve also included the openSCAD file that allows you to customize every aspect of the holder you need to make it fit your socket set. 

Instructions

I would recommend printing all parts in PET-G. I haven’t tested printing in PLA, but I’m afraid it wouldn’t be strong enough.

Even with PET-G I’m using 3 wall lines/perimeters. 

Since the parts that are stressed are pretty small, infill isn’t as important. I used a 10% gyroid infill pattern (with PET-G you should use a non-overlapping pattern). 

I’ve created a video to show some tips for assembling the socket holders.

If you want to make the best use of space (like the 1/4″ sockets in the Milwaukee case below), measure each socket and print the size holder that’s an even number larger. For instance if the socket diameter is 12.5mm , print a 14mm holder.

You make be able to go slightly over (i.e. the socket is 14.3mm and the holder is 14mm), because the two sockets on either side probably won’t fill the entire width of the holder, but be careful.
