The STL / STEP files included are specific to the harbor freight socket sets 69344 (SAE) and 69346 (metric), they may fit yours but I recommend downloading the parametric file and customizing the parameters to fit your sockets perfectly.

2 of these holders fit in the Hart Stack Organizer for which I have shared a fitting base-plate. These are just 5u tall so nothing but the base-plate is needed for them to be secured inside the toolbox.

Gridfinity Details:

• Grid size 2x6x5
• No magnets / screw holes
• Bins can be stacked on top

Parameters:

• socket[1-10]: diameter of each socket in mm
• padding: space between each socket. Could be automated but I opted to adjust manually.
