Minosharp water sharpener pin

My favorite sharpener, Minoshaft water sharpener have been broken for some time. (and sadly it looks like it is designed to fail, very small amount of material in the critical section) With 3D printer the opportunity to fix this appeared. Measured the part carefully and redesigned it slightly to assemble with the grinding disc. Printed with Bambu PLA, but everything shrunk a bit. Reprinted the locking ring with larger diameter and superglued it together. It got a bit loose in the holder, but it works again for me. I attach the Freecad model in case someone wants to scale it up for a more snug fit. Hopefully it helps someone else.
