Pontiac Vibe 2003. Thermal bypass pipe to engine block gasket. Bypass pipe is from heater core outlet to water pump inlet. Replaced thin steel gasket rubberized each side.Printed out of ABS. 100% fill, 10 layers, 0.2 mm. on a raft. You should scale it before printing to 1mm thick. Lightly washed the surface with acetone to smooth the faces, using kitchen towel.. Rinsed off in water to stop and remove the acetone wash. Use at your own risk, however ABS is good to 210f, It is compressed between the engine block and 1/4inch block. When printed the central hole is printed as ten concentric circles so good from hoop-stress point of view. Currently holding coolant in engine, under temperature and pressure of running. Update: still working leak free after a week.
