I was always annoyed that with the Vitamix Nutrion / Smoothie Maker & Blender, the remains of the mix under the knife are very difficult to get out, especially when the consistency is a little firmer. That's why I scribbled out a quick draft for a spatula.
There is probably no price for the "design", I was more interested in the usefulness.
It fits both large and small containers, I advise printing the spatula in PETG, which is a little bit more food-safe than ABS and can also be put into the dishwasher.
