The great success of my ergonomic lockable bit-screw-driver motivated me to optimize the clamping even further.

With almost 7000 downloads on my screw driver design with lockable bit holder and print-in-place free-wheel…
(get it here if you don't have it yet: https://www.printables.com/model/493064)
… I got a lot of valuable feedback. In some cases, users found that the tolerances of the locknut where simply too tight and they had to print it scaled to 100+x % to make it work. While it worked for most users out-of-the-box, I wanted to make everyone happy with the design without any troubles.
I also figured myself that the clamping mechanism did not provide enough clamping force if the nut was hand-tight. That was mostly a problem when the parts were printed from PLA, while the recommend PETG gave reasonably good results already. But I understand that many users prefer PLA, so my design was not perfect for them. Also here I figured I could do better.
I am proud to present: A further improved lock nut that fixes both of these imperfections. I hope you will be as happy with this design as I am.
The screw driver handle does not need to be changed, the new lock-nut fits to the original design (see link above).
Please leave me a like if you like it. Happy printing!
