These are Printed endcaps for the Hybrid 46 DT for 9mm and 300BLK that mimic the MP5SD suppressor cap look.
One of my 9mm caps exceeded 1000rnds of subsonic 9mm (on a Super Safe AP5SD) and quite a few 300BLK Subs (on a 16" bolt action) before i put it on a 5.56 and shot the endcap off downrange.
So they're durable enough for the job i use them for but not for higher pressure rounds like 5.56 or 308.
Mine are printed Bambu PET-CF but any Nylon should work well enough for subsonic use including multiple mag dumps in a row.
Sorry if the way i modeled the stupid 1" 27/64 x 24 thread makes your head hurt, but it's not a standard thread i could find in fusion.
F3D and STEP Files are in the release so if you want one for your specific caliber or want to edit it however.
4 or so walls and 100% infill with supports on the flared bit above the threads.
