Right Angle Screw Driver/Drill Adaptor

I have made this as I needed a screwdriver to get into a tight space and required a lot of pressure and torque.
This adapter uses a worm and gear drive so you can screw in by hand like a spanner or with an electric drill or screwdriver.
It takes the small bits found in Chinese or ifixit kits.
the 2 parts of the case are identical and the holes are sized for an m3 tap. just drill one of the sides to 3 mm so an M3 screen can pass through one side or adjust the hole diameter in the .scad file
