About this 3D model

Setting temperature of nozzle and bed, makes me do modifications all the time. Cross all the menu with the traditional Knob was annoying. I decide to do something that just can turn and turn.This is the last version of three attempts. Try it and Enjoy. I use now on my Ender3Pro and also PrusaI3MK3S. There are two STL files 6mm Knurled Shaft and Half Shaft Shank. Print and Enjoy..!!
