there are 5 models. One for each basic set of sockets in 3/8" drive and 1/4" drive, both metric and standard. there is also a model for both 3" extensions. I added more files for each with larger and bold identifiers. they should all be just under 1 ½ inches with the sockets in them that way they can easily fit inside a tool box drawer. These are based off the Hart brand sockets that are available at Walmart so they might not fit all socket brands
The author marked this model as their own original creation.
