- snaps on existing button and doesn't move at all, - taller body for easy access when AMS lid Riser is installed, - high angled tip for easier push of the knob and easier insertion of filament
Really wanted to love these but you can't get them on without lifting the AMS guts upward to give more clearance. And then once I did that, it still didn't fit proper, cracked before I could get it on? Idk maybe OP can chime in on this. Not impressed.
edit….. well they were the greatest ever until I went to close the lid. They don’t work when trying to close it. see last photo.
The best I’ve tried out of three different types. the fit is super tight and locks great into place. start from the front and while holding the AMS push it back as if your feeding filament. they’ll snap down into place.
