​

I am looking for a very small “nano level” screwdriver setup for extremely tight spaces.

Specifically, to start with need M1 and M2 driver bits where the axial length of the bit is less than 5 mm, ideally with a flex shaft so I can reach screws in awkward locations without needing a straight line of access.

Does something like this already exist commercially, or is this one of those cases where I will have to build my own custom tool?

Any recommendations for existing products, watchmaker tools, dental tools, electronics repair tools, or custom fabrication approaches would be appreciated ! Also apologies in advance if this is not the right place for such a request. Peace and Prosper 🖖
