Xiaomi Mi x Wiha Precision Screwdriver Gridfinity 4x2x6u Box (42 mm Grid)

This is a 4x2x6u Gridfinity box (42 mm Gridfinity standard) designed for the Xiaomi Mi x Wiha Precision Screwdriver set and its rebranded variants (Mi Precision Screwdriver Kit / Xiaomi Mijia Wiha, 24-bit manual set in the slim aluminium case). The original plastic inlay from the metal case drops into the top of the box so the bits and the driver remain easily accessible from above, just like in the stock holder.

The metal case lid is stored below the inlay in a separate slot with a deliberately snug fit, so it will not fall out when you move the bin. Sliding it in is a bit stiff at first, but the lid’s smooth metal surface is significantly more durable than the printed part, so this tight fit is not an issue in use. The lid is very slightly longer than the 3D printed box, but inside an organized drawer or on a Gridfinity baseplate this does not cause any problems.

The bin uses the common 42 mm Gridfinity footprint and a 6u height (approx. 42 mm tall storage section) to be compatible with standard baseplates and other Gridfinity accessories. It is intended for manual, non‑ratcheting Xiaomi/Wiha precision screwdriver sets and similar 4 mm hex bit kits that reuse the original insert.
