This model features a simple 3/8-inch drive design with an extremely low base height, allowing even deep sockets to be easily stored in shallow drawers. Although you could redesign it to achieve a snap-fit multi-segment structure, I simply printed out these components one by one and used masking tape or tie-wraps to connect them at the base. The actual usage effect is very ideal. When they are neatly stored in the toolbox, there are hardly any visible seams. To facilitate differentiation, I printed them in red and blue - red represents imperial specifications, while blue corresponds to metric specific

Each guide rail can accommodate 9 sleeve latches. If you connect two or more guide rails end to end and fix them with tape, you can also install an additional latch at the junction of the two guide rails, thereby further expanding the storage capacity.

I'm currently developing an integrated plug-in that will be equipped with a 1/4-inch drive pin, but it will still use the same base rail to ensure compatibility. Similarly, the 1/2-inch drive version will also adopt this design concept.
