This Socket Set holder is designed to fit ¼ and 3/8 drive sockets. The holder is designed so both tpyes of sockets can be mounted by mix and matching the socket adapters. The socket adapters simply slide in from the end of the model and are secured in place by the end piece as shown in the GIF below. I may update the model to support ½ inch drive, but may need to widen the base to fit the larger sockets.
This holders can be printed in either PLA or PETG. No supports are needed.
