Prusa Original Triwing LCD Knob With Concave Top

Do you like the original Prusa design, but the last know of theirs just won't cut it with the flan top surface? Here is the same thing but with a hollow as in the previous design. Does this print well? Not so much: you need support because of how the original part is designed. If you want a thing that prints better — search one here on PrusaPrinters. There are many similar designs that you can try out.
