Z adjustment wheel

This is the Z adjustment wheel I designed for my DIY drill press to mill conversion.
I started with a functional plastic prototype, and then milled out a steel one using the DIY mill with the plastic prototype.

Very comfortable on the fingers; it just makes you want to use it!

In my application I threaded the center to 1/2" UNF (20tpi) to match the lead screw.
I believe it would work for UNC thread as well. also this could be used as an adjustment knob at the end of a shaft as well.

I have also included the FCStd file as well, in case you need to edit the dimensions for your application. FCStd is the native FreeCAD working file format.
