Recently one of the three knobs came right off my drill press quill handle.
It is a plastic knob with a rubber grip coating.
The plastic barrel was cracked and broke out:
Looking at the other two knobs they are no better:
Since the ball-turner for the lathe is still on the long project "to-do" list, and I am just starting to feel almost, slightly comfortable with Fusion-360, I decided to 3D print some new ones.
I drew a flat cross section:
I rotated it about the centre line:
and added a 10mm dia. hole in the bottom:
Here it is during printing:
Done printing:
Then I tapped them M12x1.75 and installed them:
-brino
