My John Deere 955 had an engine mount fail. Made me think “I wonder if a TPU mount would hold up?” So I bought a new mount. I'm going to model it and at some point print one and see if it will hold up to a bit of abuse. The mount is a pretty hard rubber. So I'm hoping that the TPU will be stiff enough printed at 100% infill. 

This is still a work in progress. I still need to take the old one off to get the dimensions of the metal parts. 

Update, I took the old mount off and it was shredded to the point I can't get dimensions of the metal ring from it. But I was able to get the dimensions of the inner metal sleeve.
