This is a Gridfinity complient modular 1/4" bit holder designed to organize standard bits commonly used in multi-tools, hand screwdrivers, and electric screwdrivers. The model features a sturdy black base with removable colored inserts (blue, green, red, and orange) that can be easily pushed in once for a secure fit.

Each colored insert is a separate printed part, which helps save filament by reducing unnecessary infill and allows you to customize your color layout. The design ensures all bits fit snugly and remain upright for quick access. Keep in mind to only push in the colored parts once to avoid them getting stuck in the holes.

Additionally, each bit slot includes a recess for 6 mm × 2 mm magnets, allowing you to add magnetic retention to keep bits securely in place — especially useful for portable toolkits or when working in dynamic environments.
