TPU O-ring

So I had an issue with the heater leaking and found out that it was the oring being overheated or just over worked.
Had to improvise and Print some spares while waiting for the real oring to be delivered. Thius print minimized the leak but the fixed it. Since I only have 95a TPU at home, If you have 87a or softer TPU, I do think this will work, or it may depend on the application.
