This is a slight remix of Cromulent_Designs' Magnetic Paddle Shifter Ring for the Logitech wheels, as I found after printing the original, that it was far too big for my older G25 racing wheel. It took just a little trial and error to get it down to the appropriate size for the column on my G25 using Blender to modify the model, and then I had to very carefully select the magnet parts and blow them back up a bit so that they would still hold the same size magnets. I've put this on my G25 and it's working beautifully. The shifters feel much more solid now when they're pulled. Be sure that you put all of the magnets in with the polarity facing the same way so you get the same pull on both sides.
