PRINT IN TPU SO IT'S FLEXIBLE AND OIL/GAS RESISTANT
This is a replacement elbow for the PCV/Breather on a Jaguar V12, P/N#C44386
I made the top of the elbow flat enough that it can be printed upside down, no supports necessary.
Might have to use a slightly cooler setting than normal, or turn up the fan speed, or slow the print speed for the first ~1/3 of the model, to help with the angle.
