PPSH EBB shuttle part D16

This is a part I made to replace the broken piston shuttle on my own ARES PPSH, but will also fit the S&T version.
Suggest printing on its side and with 100% in fill as it's a functional part. I've used eSUN ePA-CF as I have it and need to ensure strength. But feel free to try other materials.
Part is called D16 on the ARES PPSH breakdown sheet "smg-003_expose_plan" which is available on their website.
