Alternate version here, Modular and infinitely expandable [https://makerworld.com/models/892073](https://makerworld.com/models/892073)

Just grab and go with your fingertip, 6u high, fits in most toolbox drawers. Other similar models available aren't easy to grab, and can fit too snugly. Stackable. Fits the 3x common wiha precision (maybe also picofinish?) lengths. More sizes to follow. May fit other drivers 13mm/15mm-ish in diameter. Shorter slots are smaller diameter. 15mm Pitch for your label spacing.
