Hey all,

I've been meaning to post about this for those interested, and now that I have over a year of use I thought I'd finally post my results.

Around a year ago I was interested in getting an oil catch can for my 2020 GT, and looking around at the various vendor shops I was surprised to see basically all Stinger-oriented catch cans kits were going for around $200... I'm sure at least some of these brands have exceptional build quality but in the realm of $200? Personally, I didn't see the value. Generic oil catch cans which looked fairly decent were going for only $30 on Amazon which led me to realize that the reason these Stinger kits charged so much was purely for the mounting solution they shipped with. So naturally I set out to design my own bracket, and I was going to 3d print it out of plastic.

A pretty robust plastic at least, I was curious how certain high-grade composites would perform in a hot environment, and this was a perfect test. My choice of filament was NylonX from Matterhackers, which is a Nylon/Carbon Fiber composite. The reported material heat deflection temp is 155°C (311°F), and the research I did showed that on average engine bays shouldn't get much hotter ambient temps than around 200-250°F so I decided to go for it.

I designed the bracket to fit over 2 protruding bolts on the passenger side of the engine bay that I believe are exposed even in a stock Stinger and also designed for this specific Oil Catch Can by EVIL ENERGY. This is what I came up with.

I used everything in the kit from amazon, the only thing I ordered were a couple flange nuts that fit the bolts sticking out. Everything fit together and attached pretty well, so now all that was left was to see how it performed. The cost for the OCC and the material cost for 1 bracket landed me at around $40. (I'm not including the full price of the NylonX roll, as the bracket material weight was very small in relation to the roll size)

And it's been over a year with it installed, (roughly 50K to 70k miles) and the results are basically perfect. The bracket hasn't warped, deflected, cracked... nothing. I've been on 12hr road trips with the Stinger, commute heavily in the South Florida heat, and it still looks fantastic. The Oil Catch Can has exceptional build quality and had no issues as well. Overall I'd say this was a success, and more importantly shows just how far consumer 3d Printing materials have come to have this strength and resiliency in a thermoplastic.

As for how well does it work? I'd say it works pretty well. If you have any questions, I'm happy to answer them. DM's are open too.

I have a similar setup with a bracket i made out of metal flat blank, it took some heating and bending to get it to the correct angles but it looks pretty good.
Word of advice, the seals on the dipstick and aluminum hose fittings are not good at all.....I could not get them to seal so I ended up quick epoxying them.
As soon as the CC warmed up I could smell the oil vapors when the car idled....and the cabin intake is inches away which doesnt help.
I havent had any smell since I used the epoxy.
PS: the seal around the can is the exact same size as the oil filter housing seal.
