Some knobs for potentiometers. They did fit perfectly for me but better try out one first as every printer prints a bit different. With the letters A, C, R, V, W, D, S and one blank. I printed them for a old synth i never had knobs for till now. I printed them with Prusa Slicer so i could add a different toplayer color. Have fun with them and visit my Facebook Page with visuals, robotics, programming and more stuff! https://www.facebook.com/ModularMapping

PS: I was too lazy to do all letters there but if you want you can comment which letter you need or add it yourself onto the blank one :)
