The file '1/4″-20 Workshop Knobs 3D Printer Model' is (stl,pdf) file type, size is 3.9MB.
I use 1/4"-20 bolts for almost all of my workshop jigs, so I designed this simple knob to make them easier to adjust.
The knob is 2" wide and 1" tall. It accepts a 1/4-20 hex nut in the middle (7/16" wide).
I included both rounded and chamfered versions, but I think the chamfered ones look better and print better.
