I modeled this KitchenAid pusher in Autodesk fusion since the one that came with my KitchenAid food processor was broken. It seems that this acrylic that they use for the pusher is very brittle. I modeled this for any thermoplastic, but I printed it in woodfill . I also considered using PET since that is more "food safe approved". However I don't think PLA is very toxic either given when I know about it's chemistry. This should work for model KFP0722ER, but I believe it work for other models as well.
