Secure, easy fit and remove Locking AMS Saver.

Over the last 6 months or so I downloaded and printed 7 different AMS Saver designs all of which have failed in one way or another. A couple were needed brute force to fit and even were worse to remove, others tended to work loose or remove themselves.

I've been running with my design for almost 2 months now and they are solid as a rock. The 2 part construction and optimised base design is easy to snap into place by hooking the retainer over the front and slipping the flexible ring over the button. Then the button cover slides over and locks it securely into place.
