Background
I kept on experiencing the dreaded "AMS assist is motor overloaded" error when I used certain filaments (Inland spools, Inland refills with Bambu spools, and sometimes with Sunlu spools). I noticed that the filament would get trapped on the left side edge right before the error popped up.
This printed part helps to wedge the filament so it won't get stuck anymore. It's designed to work with the Bambu Labs spools. I created a second model with a reduced size to also work with Sunlu spools. However, I want to note that I haven't had a chance to test the Sunlu version yet since I haven't gotten the error lately.
Specifications
I would recommend printing this with 100% infill. I printed mine in PLA plus and it has been holding up well so far.
