Is it in two parts? Looks to have a join at the short end.
My first thought was C8 spacer simply because it’s the most recent new item I have seen being discussed, but when I saw the join I had no idea. And the tapered ends made me think it could be for something that requires a press fit.
Ok, previous photo was not good, it was hard to determine real size, also my phone have big problems with color rendering over this green pad, so most of you confused the material.
Dang, I was completely wrong with the scale, I thought they were at least twice the size they are. I was on my phone and I would have bet money that it was in two parts, glad I didn’t! :person_facepalming:
I had some requests from members for making quad to fit Kathod optics. I decided that M1 is the best host for this optics. Anyway, I dont think it is several times better than Carclo (but it is several times more expensive).
I made 15 pcs only and think this is all. I can make make more if we need at least 5pcs, or share drawings with someone.
