Modular slot inserts for Whity's shallow height rugged box, designed to hold driver bits. There are two versions available, one single-wide (1x2) and one double-wide (2x2). Two double-wides or four single-wides will fill the entire box. These are quite shallow to allow bits to easily be pulled out. You will need foam or some other padding inside the lid of the box to prevent short bits from falling out if you turn the box upside down, but this was the only way to allow longer bits to fit.
The author remixed this model.
