I made first full model of my KJW HiCapa KP-05 (front parts) and then design that adapter to around it. I used Fusion360
Its printed from PLA cause it was just
...Zeig mehr first prototype, it was tight but I warmed it with lighter so it fit to its place well.
I recommend use PETG to end part, I'll add fixed model someday, but this is working with just little warming.
