Installation instructions:

1. Apply a small amount of strong adhesive to the grooves of the 3D-printed wrench.
2. Insert the corresponding hexagonal screw into the groove, ensuring that the hexagonal groove of the screw is perfectly aligned with the internal shape of the printing groove.
3. Press the screw firmly into place and verify that it is perpendicular to the handle of the wrench.
4. Apply a second layer of strong glue to the bottom of the screw to completely fix it.

After curing, your customized Allen wrench is ready to use.
