3D Printer Gear Knob with Fine Tuning Dial

My Anycubic Kossel Pulley 3D Printer has a hyper-sensitive knob that can make navigating the menu and setting precise temperatures mildly frustrating. I decided to fix that with this new knob that has a second dial for fine tuning. It uses a reduction gear to slow down the turning.   Depending on your printer, the parts may snap together, or you might have to use an adhesive for the two halves of the body. I also used 3M VHB tape to stick the body to the printer. See my video for details :
