When a friend contacts you and asks for help because their 2 year old spiked their favourite toy into the ground and broke it there is only one thing you can really do. Ask for very specific photos with some sort of measurement, get the image into Onshape and make a replacement turbine in clear PLA.
Fits like a glove and the little boy now refers to me as the “Doctor” as I can fix broken toys. So it's win win.
The author marked this model as their own original creation.
