MK3S Control Panel repair Knob

My knob was loose on my mk3s+ so I removed my rattly knob and thought hey I just need to widen those little prongs a little bit “snap” aargh #$@! hmm that's a fail. 

So now my knob won't work with just one prong at all! 

I have a 3d printer so I remixed the original and printed it up and here it is. 

It fits nice, is well centered and seems to be just like the original. 

Its nice to be able to fix things! 

I am so happy my printer is whole again!
