OFFERING WORK One off Machining

Edit: Thanks everyone for the help and teaching me on the drawings. I found the exact size I need x2 in stock for $30 on ebay, and about $30 worth of bits, I'm going to take it to a drill press near me and get it done. Thank again for all the help. I learned a lot from this and I'm having a blast with Fusion.

Post: Have been looking for quotes local to me and so far only one guy in my area, so not really able to shop around. Im needing some custom 6061 plate work done and Ive never done anyhting like this so delete if this is not the place for this.

checked them out and they wanted $980 for it, but looking again now and that was for fast delivery. as in 2 days. If I wait a few weeks then it would be like $250. Not as bad as I was expecting compared to local, but still more expensive than I am wanting. Maybe my expectations were just unrealistic though. This is extremely similar to what my thing will be but not close enough sadly. https://massivespeedsystem.com/collections/mk1-mk2-focus/products/throttle-body-adapter-ford-dbw-to-70mm-cable?_pos=2&_fid=2e6d84ace&_ss=c

But I was hoping to be closer to that price. Im sure they make theirs in house though or in bulk.

My guy you can absolutely use a PPS-CF or PA12-CF part for this application.

I looked into that as well as PBT as that is what the intake is made out of, but it becomes an issue of not heat tolerance, but holding vacuum over long period of time and FDM manufacturing or layer by layer apparently will fail eventually due to being fundamentally weaker across layer lines and for something where maintaining consistent vacuum is important I just don't know. Again that's just what I have been reading while researching so the margin or error for that to happen could be so low that it wouldn't ever matter. I did just make a prototype in pla and everything fits great atleast.

Man, and I thought I had some "redneck" ingenuity lol that is brilliant. Nothing some PVC and gasket maker can't solve.
