After @sledmanjones pointed out a different extruder bracket in this thread I started poking around for a better design, since a lot of people were reporting that theirs were breaking pretty quickly.
I found this one, with a ton of downloads and a perfect rating. It’s a remix of a couple other designs: X1 / P1P PTFE Tube Guide
I printed it out in PAHT-CF, and haven’t had a single AMS reloading issue since. Only takes a moment to install.
