I advise PETG or ASA for the angle under load otherwise PLA will work just fine for the other parts, tap the 2 holes in the angle with M6 and use M6x16 hex bolts or just drill 6mm thru and use a bit longer bolts and nuts on the other side, then you will be able to unscrew the feeder and give a wash and place it again easy.
