looks great, just needs a few hundrad heat cycles with different fuels&oils/lubes & pressure to see how they hold up. also try breakleen!!&carb cleaner too. you may even ba able t make some seals out of it...like old car seals for ac/heater fresh doors. or vent seals as well as many more, like seals used for paint protection on items that are bolted to the car like lights&such or door lock seals etc. and if it comes in different colors thats awesome for "color matched seals" keep up the great work!! I wish I were smert enough to do that stuff, I would probably be printing intake manifolds and much more.
