I tried some shrouds but they wobble and don't feel good.
Also the Zius only supports the barrel at one end, creating barrel wobble.
This shroud fixes that.
Use M5x8 button head screws to attach to the blaster (a spacer is provided, M5x6 MGHT fit, but they need to lock into the Zius's barrel holder). If you use the optional picatinny rail, that will need an M5 countersink.
Use M-LOK hardware to attach the stabilizers. (I got mine from Taobao and they appear to be regular M4 screws with a custom nut).
Use M4x16-18 countersink to screw from the stabilizer against the side of the barrel. No nut is required as the print has a tapping sized hole. Tighten until you hear or feel the metal scrape, then back off ½ a turn, then after all 4 screws are in, gradually tighten from opposite corners. You can put a cap on the end of the screws if you don't want them scraping your barrel.
To attach the BCAR you might need to dismount the shroud depending on your BCAR. This is an area where this project can be modified. Please let me know.
Print orientation note: I test printed the shroud standing vertically on the rear (blaster) end with tree supports.
EDIT Added .step files
EDIT Updated instructions, I tested with M5x8 and I do not know if M5x6 fit.
