Qidi Tech Acrylic Printer Cover Filament Guide / Acrylic Straightener

My filament guide tubes were hitting the corners of the acrylic cover and the acrylic was bending a little while not maintaining its original intended shape. I created these Acrylic Straighteners / Filament Separators / Guides to assist and it seems to work quite well so far.

One has a flat center, while another has a slightly raised center.
