T8 8mm lead screw bit for z-rod

This is the hex screw bit (1/4 inch) with the 8mm hole, use it with the cordless electric screwdriver to move the z-rod T8 lead screw nut (or x carriage attached to the screw nut).
If the number of sides is 6 for the rod holder then it becomes a nut driver bit. Otherwise, default is 64 for T8 rod holder. The height is applicable for the hex bit part and the rod holder part, so the real height is about double that.
Printed using PLA, 40mms, 100% infill, and brim 10mm. Support not needed.
