My Grandmother has an old Blender (made in 1999). A few days ago, she told me that it doesnt work anymore. I took a look and found that the drive coupling was completly worn down. First I tried buying a replacement knife, but after 24 years, there are no replacement parts availabe (understandable). So I removed what was left of the drive coupling and designed a new one. 

I would suggest printing it out of TPU to reduce vibrations, since the original part was made from some kind of rubber.
