Built these trays to hold an Craftsman and Kobalt ratchets, the extension, SAE sockets , Metric sockets and a few socket adaptors. Each tray has opening for connectors so all the different tray stay together and do not shift in my tool box. I have also posted trays for ΒΌ Drive rackets and sockets.
The author remixed this model.
My tool tray were inspired by many designer including https://www.printables.com/@hatleyt.
