If you already bought Xiaomi Precision Screwdriver Set and for no reason, the plastic lock of the aluminum box has been broken you need to print this folding box and simply insert the bits box inside.
This design consists of 4 parts:1) Main body2) Folding lid3) bottom lid4) Tiny screw container lid
The hinge of the box is designed separately ( print-in-place is also possible but might face difficulties in print) and you must insert the hook shape section of the folding lid into the hinge, because of that I highly recommend print in a standing position (Shown in the uploaded picture) to prevent hooks from broking while inserting into the hinge.
