This is a rather lengthy rail to lay down your Impact sockets if your toolbox has less height in the drawer you put them in. I have provided several ways to print it, including an untested dowel option. I printed it in 3 parts and simply just let the weight of the sockets and the amount of organizers keep them together. The 32 is a little tight, but the tiniest amount of sanding got the clearance correct, so I found no reason to fix this. This was made specifically with the harbor freight impact sockets both deep and shallow in mind, with additional purchases from craftsman to furnish the empty slots.
