This is simply a handle to fit one of the little screwdriver nut adapters you get n some PC case fixing parts.

This will turn it into a nut driver for use in other projects.

Just glue in place in the end, you may need to warm the nut slightly to press it in (not melting hot!)

1.2mm shell 25% infill. Use a brim or raft if needed, it will be relatively small.
