knob 1/4in with tee nut

thingiverse

There a lot of knobs floating around and majority use hexagonal nuts in conjunction with them. Which by all means not bad thing but I do have a lot 1/4in 3 prong tee nuts laying around. So I thought why try to use them with a 3D printed knob. Here is my first go at it. It's a simple knob with recess to accept a 1/4in tee nut. My tee nuts have a diameter of 3/4" on top and the shaft has a diameter & depth of 5/16". You will need bend the prongs straight if they are bent prior insertion. Just couple light blows with hammer will drive the nut in. When tightening the knob on an actual bolt it will drive the nut in even more. The fit is tight and it should not fall out with normal use.
