Thanks for posting this- it seems like a good solution.
I have McGyvered something that I think will work for me but I haven't assembled everything yet. How much will you be asking for the 3D printed ones and is it just the retainer you're selling (without the bearing and other hardware)?
I could do just the retainer, if it matches the dimensions on your bearing. The whole set would be the retainer, bearing, two set screws, and two nuts. I was planning $55+ shipping. Could do half for the retainer.
Wish I could do less, and it still be worth it...
I know people think all 3d prints are cheap, but this stuff is $120/kg, needing to be really heat resistant and strong. Also 6 hours of printing for each part.
Just by looking at videos and pictures, It looks to be fairly close to the exhaust manifold, and I'm wondering if that's why they fail so commonly, because even long periods of moderately hot temperatures will anneal it and make it brittle.
