The file 'Knob 3D Printer Model' is (stl) file type, size is 57.0KB.
Here is a knob I designed. No specific size. it would require some attention to the design if needed but I am happy to update if someone needs to make one, just comment and I will answer. We see these knobs a lot on photography lights and camera gear but I have also seen them on car roof racks. I am happy to alter so just let me know.
