Other Issues:can't be used on an ams hub, I just shave off the side to fit, but upon printing non stop,i saw the poop didn't shoot out and I manually pushing it even the printer is still extruding the filament, then I found out that the cover is blocking the poop when I uninstall it all poop came out. hope its just me. still thank you for the effort, nice design but need to redo the dimension, & if ever theres gonna be a new update hope you can include a stopper so the cover won't slide off.
