UPDATE 2024-03-23: I Added Half_to_Quarter_Inch_Handle and Half_to_Quarter_Inch_Pin STL files which just resulted from changing the min/max values of the wrench to these sizes:

I'm calling this a remix because the idea came from Ed Johnson's model (https://www.printables.com/model/89991-hex-wrench-driver-parametric). I liked the idea, but I didn't like that you had to print a different one for every wrench.

So, I checked out his Fusion 360 model and used some of the ideas in recreating my version from scratch. The parameterized Fusion 360 file allows you to specify min/max wrench diameter along with the diameter of the handle and a few other things.  It's heavily parameterized, so you can do what you want with it.

The 3mf/STL files (and images) I uploaded are using min/max of 1mm/6mm and the handle diameter of 50mm.

You should be able to print however you want. No supports needed. I printed at 0.35mm resolution w/ a 0.6mm nozzle.

If you don't have Fusion 360 and want other sizes of this, let me know and I'll upload them for you.
