I'd take the top box off and find a convenient location elsewhere. Just my general preference I prefer to put tools I'm working with on top rather than crowd the limited work bench and table space.
So put it on the workbench and take up room with tools where real estate is needed instead of leave it on top of the tool box stack and fill it with tools... :rolleyes:
How's that going to save space... Robbing Peter to pay Paul... :realcrazy:
