M6 threaded device foot/knob

All you need is a toothed knob with an M6 screw and an M6 nut.
To improve the print quality, a solid structure was reserved during the design process. All that needs to be done is to drill it out and then screw in the screws.
Moreover, I also thoughtfully installed an M6 washer under the screw head.
