This design is a slightly altered design based on the cat collars made by Ancol:
The frustrating thing about the original collar is that the plastic part can break relatively easily and there was no way to replace the broken part; usually a fork from the side of the "trident" piece.
In making a replacement, my primary aim was to be able to retrofit into a broken buckle. The webbing part is virtually unbreakable, though ultimately with the "I am microchipped" text also being slowly rubbed and scratched away over time, you'll probably still need new collars from time to time, but maybe slightly less often.
Hopefully assembly is intuitively clear. The buckle has a custom support layer designed in, which can be easily broken away once printing completes.
